bad_service never fail to disappoint, really.
ariel770 got a Canadian penny in her change. She does not like it.
I went to Radioshack this weekend to buy a phone charger for my car. My total was like $21.88. I hand the man $22. He hands me back a dime, a penny and a Canadian penny. I looked at it and said, "This is a Canadian penny." and attempt to give it back to him. He looked at me and said, "So?"
"So?!?!? Asshole I live in freaking Missouri! What good is a Canadian Penny going to do me? It's not legal tender here so basically you just cheated me out of money!"
Of course I didn't say that I was just too stunned I walked away
Because obviously no one in the history of US currency has ever received a Canadian coin or two in their change. The poor dear is financially ruined.
Responses range from making this point many, many times with varying levels of snark and/or profanity to supporting the OP's horror to pointing out that the bad service came not from the OMG FAKE MONEY but from the cashier's attitude.
