Somebody Took An Evolutionary Detour

(The waitress is trying to take our orders when a customer from the next table rudely interrupts.)

Customer: *interrupting* “Is the fish suitable for vegetarians?”

Waitress: “Excuse me?”

Customer: “The fish. Is it suitable for vegetarians?”

Waitress: *very politely* “No, it’s meat.”

Customer: “But it doesn’t say that there’s any meat. It says fish and chips and peas.”

Waitress: “The fish is meat.”

Customer: “No, it’s not. Only mammals have meat, like cows and chickens.”

Me: “Chickens aren’t mammals.”

Customer: “Of course they are; they have meat! Honestly, don’t you know how rude it is to interrupt somebody else’s conversation?!”
