Art Schultz, better known as the Senpike Mall's Santa Claus, carried out the management-issued directive to push fine china dinnerware during dozens of two-minute lap sessions Monday. 'Ho, ho, ho! Has Bobby been a good boy this year so Santa can bring him, a, uh, Wedgwood five-piece bone china setting in the timeless 'Crown Gold' pattern?' Schultz said to perplexed 5-year-old Robert Ullings. 'Maybe if you're on your best behavior, and a big help to Mommy, Santa could bring you...a Lenox gravy boat!' Schultz bolstered his holiday messages by urging children to act now, as their good behavior could qualify their parents for a 10 percent discount on their first Nordstrom credit-card purchase.
