Today I went to a restuarant I love and used to be there every day (long ago my mom worked there as a waitress for like 15years) I always tip 20% or more, tips kept food on my plate as a child and a roof over my head. I'm an adult now and know how important tips are in our service industy. That being said, when I arrived at the restuarant I ordered a tea as a beverage. I received the tea by a nice woman around my age, thinking all is well I began to drink my tea. That's when I noticed there was food in my glass (a small piece of lettuce, I hadn't even ordered food yet) I immediately felt sick, but I really wanted this places food, so I showed it to the waitress who apologized and gave me a new glass. I inspected all of the dishware I received after that. After eating and receiving the bill, I saw that I was being charged for the drink. I dont like confrontation so I just paid and left a note on the receipt that said "Dont serve a customer a drink with someone elses food and then charge me for it!" with a 0 on the tip line. Am I the asshole for stiffing?
