The Long and Short of It

Sometimes there are some interesting things that happen at my place of employment that make me laugh and wonder if people have a brain. Of course I cant laugh at them since I have to act professional. Today a customer was trying to pay for some things and she handed over her id and credit card. Her name did not match the males name on the credit card and he was no where in site. So I called her on it and she said it was her husbands card so I asked if she had any id with a matching last name on it. She said no. I asked if there was a way she could verify that was her husbands card so guess what she flashes in my face.....her wedding ring! Seriously!!!!!! How can I verify the guy that bought her that???
