"Sorry I was late for my appointment. I got stopped for speeding, but it turned out ok 'cos the cop gave me a citation!"
"So you got a speeding ticket on the way here?"
"No, it was a citation! I guess he thought I was driving ok, even if I was going fast."
"Citation means ticket."
"No, it doesn't, see??" while pulling ticket from his pocket.
"It's a ticket. Right here it tells you to pay the fine or go to court."
"That rotten bas....! He said it was a citation!"
