I often will grab a stray cart and either drag it inside or to the carousel; especially if they are someplace where it looks like they might get run over. I never use one though... it's a way of controlling my grocery bill.I never take the cart to the carousel; just leave it against the post by the handicap parking spot, out of the way of anyone parking, of course. When I park in a handicap spot, I love it when there is a cart sitting right there so I have something to hold onto walking into the store. I see people all the time park, whether in handicap spot or not, walk right by carts without touching them to go into the store and get a cart there. I don't understand it.
