Several times when I was in a hurry and did not check the change that the cashier gave me, I had accepted coins from other countries. These coins looked like our country’s 10 cents and 20 cents coins. I only realized that I was given the unusable coins when I inadvertently gave them to the cashier and was told off by the cashier. I remember scrambling my coin purse to find other usable coins but found a couple of for army coins too. Some people can really cheat their way out of the check-out counter.
