Casino Royale
Once, A lady came through and handed me all $1 coins. Upon inspection, I found that these coins were not legal US currency. They said “Good for One Dollar” on them. No “E pluribus unum” or anything. They literally looked like tokens you would get a game room.
We had received this type of coin before and I had been instructed not to take them. So I told her that they were not US currency and that I could not accept them as payment and did she have anything else.
She proceeded to tell me she got them from the bank (she clearly did not) and refused to pay in any other currency. After a few more calm replies from me, she screamed at me an asked for a manager who told her the same thing. Sorry lady. Go back to the “bank” and get some real money. Thank you.
