What I realized about grocery shopping

I realized that no matter how long I look, or how many I test, I still manage to pick the messed up shopping cart. You know - the ones with the squeeky wheels or one wheel that gets stuck and doesn't move. I wonder - are all the carts like this? Do I attract broken carts? Or is this a funny prank by all supermarkets? Do the employees have a blooper reel of innocent shoppers trying to maneuver carts that they watch on their breaks? Hmmm
