I’ve seen little old ladies with their backs bent like boomerangs able to return their carts and fully abled people jam their carts into the nearest hedge. Sometimes being abled or not has nothing to do with common courtesy.
I was attempting to strong man his, erm, "argument." I am fully aware of the dickheads who just leave their carts wherever and have zero regard for anyone around them.
Being an asshole isn't a disability.
