MARK: Are you trying to tell me that I actually have to pay for “free” wireless access?
CASHIER: First of all, sir, it’s not “free” wireless — it’s free* wireless.
MARK: Again with the asterisk! Look, there’s no difference! It means exactly the same thing!
CASHIER: Not it isn’t sir. You said “free” — you used quotation marks, as if to cast the word in doubt. I said “Free*”, appending an asterisk to the word, which means something completely different.
MARK: What does it mean?
CASHIER: “You can’t sue us when you learn the truth.”
