Target, about 5 years ago. My two sisters and I had the job of 'running' to the back of the store for polly pockets. My mother's job was to get a cart and meet us back there so we could have a place to put our bargains.
We concord the isle (fast runners) and started looking around a little. My mother shows up all out of breath and red faced. Asked what was wrong, all you had to do was get a cart and meet us here. Well, she got in a fight with some lady who kept trying to run her over with her cart and my poor old mother finally turned to her and said she was going to deck her if she did it again.
Oh the best part, when we were checking out, my mother spots this person that was trying to run her over, and yells, there she is!!!!!
Now when my mom has cart duty, we ask her not to get into a fight over it.
