I had a bill of 5.01 the other day and handed the clerk a ten and a nickel so I would not get all that change. She handed me back 4 dollars and 99 cents. I started to complain and she stopped me. She said the other way is too complicated
She told me I was free to shop at another 7/11 in the Metro area.
At least she was courteous .
I have a piggy bank where I put loose change. It all evens out.
