person A: Security at the grocery store followed me to my car the other day.
person B: Why did they do that?
person A: I had opened a soda while shopping and did not pay when I checked out. They thought I was stealing
person B: Oh shoot. Did you forget to pay?
person A: I did. I wish the check out lady had reminded me. I wouldnt steal a soda.
person B: I am sure that was embarrassing. Just a mistake. 
person A: It was. That has never happened to me before. People were staring.
