Whenever I draw money from my bank account (on the rare occasion that I am able to do such a thing), the teller will ask, "how would you like your cash?"
"Err, legal tender will be fine, thanks."

(I will be slapped one day )

Or, you go shopping and buy, like 5 items, and the till wahler will ask, "would you like a bag?"
"Err, no thanks, I like dropping my stuff on the floor every 5 paces."
