PARIS: I don’t have enough change.
RORY: Pay me later.
PARIS: What am I, your versateller?
A versateller is an automatic teller machine (ATM); the word was popularised by commercials for the Bank of America in the 1980s. Some people still prefer the word to the more common ATM. The name combines the French for “pay” with the word “teller” (usual American term for a cashier).
