My wife is Celiac. So, really intense real gluten “allergy”.
We get a gluten free menu. It lists chicken and waffles. She orders it. Takes a few bites. Comments that it’s the best gluten-free waffle she’s ever tasted. Starts to feel sick. Asks the waiter. “Oh, the waffle isn’t gluten free, just the chicken.”
We got home and realized neither of us had paid the bill.
Went to a Pizza Hut in my town for a school trip when I was 13. A friend thought he was being funny and put a slice of pizza under one of those rubberized table cloths they used at the time. About a month later his grandma took us for his birthday. The pizza was still there. I don’t go to that Pizza Hut anymore.
