To catch an accidental thief
Once I was going to meet up with my BFF at the mall. We were meeting at a store and I got there early. I was looking at a pair of pants when I saw her walk by. I tried to yell but she didn't hear me, so I ran out of the store after her, still holding the pants. The alarm sounded and all of the employees in the store started running after me, because it looked like I was trying to steal the pants. Everyone in the whole mall stared at me and the cops even came. It was the most embarrassing moment of my life.
