Some people at Walmart will make extra effort to jam one up on a curb rather than return it

I’ve seen it at grocery stores too

They have to lift the cart as opposed to pushing it

At least it won’t roll into someone’s car.

It isn't extra effort -- you just put your foot on the rear axle and "wheelie" it up -- I've done that during horrid weather. It accomplishes the purpose of protecting other's vehicles.

On the subject of preventing paint or ding damage: Walmart's carts, at least around here, are about the only ones that don't have plastic bumpers on the front edges of the carts. That seems like mild negligence to me. The metal corners will do damage every time. I just spent about 40 hours repairing a quarter-sized ding/dent. Took so long because of re-dos to get it perfect. It is perfect now and you can not detect a repair even when looking at the area from a shallow angle with various lighting. Glossy black cars are tough to do body and paint perfectly.
