But pleasing  a customer should have its limits! The Christmas party at the Boston branch of Hartshorne-Logan was threatening to become more legendary than usual this Christmas. The farm machinery manager had already collapsed. When he slid under the table containing the drinks, Miss Pringle, who sold millinery, had screamed: "He'll drown!" One out of every three dirty stories started by party attendees had remained unfinished, because each had reminded someone else of another story. The recently developed liquors which affected the bloodstream three times faster had driven away twinges of conscience about untrimmed trees and midnight church services. glass splintered against the floor. The noise caused a temporary lull in the gaiety. Several employes even felt a passing suspicion that things might be getting out of hand. "It's all in the spirit of good, clean fun!" cried Mr. Hawkins, the assistant general manager. Since he was the highest executive present, worries vanished. Everyone felt fine. There was a scurry to shove the broken glass out of sight and to turn more attention to another type of glasses. to its place until new glass could be obtained. But the fall had sprung the frame at one corner and it wouldn't hang straight. "We'd better put old H. H. away for safekeeping until after the holiday," he told a small, blonde salesclerk who was beneath his attention on any working day. With the proper mixture of respect and bonhommie, he lifted the heavy machine. another!" Milly snapped out of it. She giggled, suppressed a ladylike belch and returned to reality. Looking at the envelope, she said: "Oh, I see. They must have stuck it in to tighten the frame. Gee, it's old." Mr. Hawkins had refreshed himself. He decided that he liked Milly's jovially, "Hey, people! You're all fired! Here's an order that Hartshorne-Logan never filled! We can't have such carelessness. This "Best electric doorbell. Junior detective kit. Disposable sacks for vacuum cleaner. Dress for three-year-old girl." She turned to the assistant general manager, struck with an idea for the first time in brightened. "Unless—" he said it loud enough for the employes to scent a great proposal and the room grew quiet—"unless we broke the rules just once and used the time warp on a big mission!" There was a silence. Finally, from an anonymous voice in one corner: "Would the warp work over eighty years? We were always told that it must be used only for complaints within three days." "Then let's find out!" Mr. Hawkins downed the rest of his drink and stuff that's on the order. Get the best of everything. Ignore the catalogue numbers—they've changed a hundred times in all these years." Milly was still deciphering the form. Now she let out a little squeal thrill the old girl. We wouldn't have vacuum sacks any more. So we'll substitute a manky!" therefore hadn't been broken in shipment. Ann sighed and picked up her bundle. With a last look at the lovely spring afternoon and the quiet suburban landscape, she went into the house. open the parcel. "Now I'll have to write another letter to explain that they should throw away my letter of complaint," she told her daughter. "And by the time they get my second letter, they'll have answered my first letter. Then they'll write again." Out of consideration for Sally, she omitted the expletives that she wanted to add. "It's probably the wrong size, too," Ann said, pulling off Sally's dress to try it on. "Let's find as many things to complain about as we can." to look vacantly at the distant wall. "We'll have to send it back," Ann said, "and get the one we ordered." early." "Les! I'm going crazy or something. Sally just—" wire." for a wall socket. "That's funny," Ann mused, her mind distracted from Sally for a moment. "It looks terribly expensive. Maybe they sent door chimes instead of the doorbell." Ann immediately felt better. She put her hands behind her back, pulled off her ring and slipped it into her apron pocket. Les was sentimental about her removing it. "I'll get dinner," she said, trying to keep her voice on an even keel. "Maybe you'd better start a letter to Hartshorne-Logan. Let's go into propulsion. hips, looking at the front door, chuckling. "Neatest trick I've seen "Oh. Something like those name cards with something funny printed on them, like 'Another hour shot.'

"Sally is so excited over a new dress that she's positively feverish. Let's see now—it was sugar that you want, wasn't it?" kitchen table. "Excitement isn't good for me," Mrs. Burnett said testily. "I've had a lot of troubles in my life. I like peace and quiet." "I think the Detectolite did it," Bob said. "The instructions say you've got to be very careful with it, because its effects last for a long time." that dress herself. Where did she get that nightgown?" it's the same dress. It must change color or something when it's time for a nap. It seems impossible, but—" She shrugged mutely. "And I think Sally's running a temperature. I'm going to put her to bed." keeping her balance with difficulty, as Sally threatened to pop upward out of her arms. The whole family decided that bed might be a good idea, soon after dinner. When the lights went out, the house seemed to be nearly normal. Les put on a pair of gloves and threw a pillowcase over the eyeball. Bob rigged up trestles to warn visitors from the front porch. Ann The only good thing about the morning for Ann was the fact that the manky had quieted down some time in the night. After she got Bob to out on its side: " Today is Wednesday. For obvious reasons, the manky will not operate today. " order as soon...." Ann crumpled the letter and threw it into the imitation fireplace, knowing perfectly well that it would need to be retrieved for Les after claims it was just accident that he tried it out when he was walking by the gym during calisthenics. We've had to call upon every family we believe that we can expel him quietly without newspaper publicity involving his name, if you'll—" "It's apparently an allergy to some new kind of material. But I don't they're stopping here." "Oh, no," Ann breathed. "Something's happened to Les." "It sure will," Les said grimly, walking into the bedroom.
