What was your worst Karen encounter?

Showed up for my shift at the home improvement store. There was a big sale going on, the line was long. Karen runs over to me demanding something from way up high. So I walked over to the rolling ladder and she grabbed it out of my hand, yanked it sideways took off running with it screaming that she's been waiting. Superman himself could not have got it fast enough for her. I was like don't do that lady! "I wanna talk to your manager!" so I pointed to the other side of the store and said the managers office is over there...she took off sprinting all the way across the whole store to complain on me. She never came back and later that night the manager and me had a good laugh over that Karen.
