Petty theft for fun and profit
I was at Subway yesterday, and the woman in line ahead of me ordered a couple sandwiches and a drink. While I was paying, she came back to the register and asked for another cup, saying she dropped the first one. Then she went to the drink machine five feet from the register, in front of God and everyone, and filled both cups.
And she had a kid with her. Nice example, lady.
Did you say anything to her? You should have politely relieved her of the 2nd cup.
