When food hits the pass and you bring it to the table, you know who ordered what. You do not stand at the table holding a plate asking "who had the burger?"
Auctioning kills the moment. A killed moment drops the tip from 22% to 17%. On a $70 check that's $3.50 in your pocket every time it happens.
If you don't know who ordered what, ask the kitchen, check the ticket, or check with the server who took the order. Never ask the guest.
