Bad Attitude

As I stepped away from paying at a till point I realised I forgot to ask for a gift card so I went to the very next till point. I asked Monica if I can purchase a gift card and she told me I must go back to the back of the queue. I was shocked and asked her how does that make sense when I just paid but forgot to pay for one more thing. A guy at the next queue told her I don't have to go back to the queue. Monica then turned to look at me and asked me if I was going to cry, she laughed then walked away to get a card.<br> <br> I don't see how any of this is funny because had it not been for the guy, I would have gone to the back of a long queue unnecessarily.
