Now my father, he takes two 4 mile walks a day. His route brings him by a supermarket in NJ. He takes ALL the stray carts and brings them back to the cart area...and unleashes the quarters that you need to deposit to get a cart. My dad has done this for years now and has amassed hundreds in quarters.
I doubt the shopping cart test is a litmus test for anything
however, I will say it's interesting that I will consider not putting it away if I'm in a bad mood. If I see a gathering of carts in the improper place, I might add mine, if the designated spot is far away or there's obstacles/ traffic in the way.
I always put it back, and I'll take any other scragglers I see nearby as well. I've had at least 3 stray shopping carts get blown by wind into my doors while I was inside shopping. And nothing is more annoying than starting to pull into an empty spot and there is a shopping cart left there or blown by the wind there.
but it gives me way too big of a boost to my self esteem and super ego, every time I do it. It's way out of sync with the actual action.
Like you'd think in my brain, I just rescued a baby and a dog from a burning house. I kind of expect people getting into and out of their cars to stop and applaud me.
