It is a part of the thrift store life, unfortunately.
I did wait until he/she left before I said something to the owner's wife telling her I thought she was unfair. I didn't want to make it angry, because they might look like a woman, but they will hit you like a man when they get mad.
Her response made me laugh, she said, " You are going to straighten that out with him. I mean her."
So, the owner's wife like me can't figure out what it is either.
