"I forgot my wallet," you explain to your server. "Is there any way I could just run home and get that then come back to pay? I'm not trying to scam you, I just...well, sorry."
"I understand," the old woman says. Is this Mom? "I'll just need some kind of collateral to know you'll come back. Can you leave you ID here?"
"Sure," you say, "that makes sense." You take out your wallet, remove you ID, and hand it over to Mom.
Mom looks at your card then back up to your face.
"Forgot your wallet, huh?" she says. You protest, try to explain that it was a mistake, a misunderstanding, but she's not listening to anything you have to say. She's focused on dragging you back into the kitchen by your hair. Once there, despite your continued pleas and cries, she dunks your face into the deep fryer and holds you there until you stop flailing, which is not terribly long.
