Conversation I had at Trader Joes

INT. TRADER JOES
I'm at the check-out line having just ran my credit card through the credit card gizmo and advised it that I would like ten extra dollars back.

CASHIER
Ten dollars back?

ME
Please.

CASHIER
How do you want it?

Slight pause.

ME
I was thinking cash. Yeah, cash would be good.

He didn't think it was very funny. I, however, laughed and laughed and laughed and laughed.
