Sorry dude, your true feelings are already out. I’d never trust you to NOT do something disgusting to my order.
While working my way through college I was a busser and a waiter and the one thing I learned was to never piss off people who handled your food. While ordering at drive throughs my girls asked me why I was so polite and I explained it to them with examples. I would never buy food off someone who has presumptively revealed his bias towards me.
I hop that this asshat’s restaurant folds.
