I once made a cashiers head nearly explode by refusing to give her a phone number over the counter to pay cash for a shirt.

“But I need it!”

“No, you really dont.”

“The system wont allow the sale without it”

“So enter a bunch of random numbers, I dont care”

“I cant do that”

“Why?”

“Because then some random person will get texts from us.”

“Ok”

“So can I just…”

“Nope. I exchange money for shirt, thats how this works.”

“Ummmmmm” Smoke starts pouring from ears
