"No, you do it!"

It's the week before school starts and everyone is shopping for school supplies. Stores are crowded! We were in Wal-Mart yesterday evening (imagine that) and when it came our turn to check-out the cashier looked at me and asked that I turn around and tell the lady in the blue shirt (who was third in line) that she was "the last customer". There were several others behind her, too. I turned around hesitantly and said to myself, "Is this my job to do or hers? It's kind of scary." So, I turned back around and looked at the cashier with a smile on my face and said, "I think you should be the one to tell her that". The cashier looked at me and "Oh, no...I'm not gonna do it". I guess she's still on the clock right now scanning items....weird....
