Working as a waiter at reasonably expensive italian restaurant.
Bring some rich dude out his pizza, he calls me over 5 minutes later and said he found a nail in it (hammering nail) from the wood in the pizza oven.
Dude is fucking angry.
My smart ass 17 year old response, "you didn't ask for no nails, only no tomato"
He loses his shit, nearly chokes me with stereotypically huge italian gold jewelery
