I used to be a manager of a WM that had four of those carts. One family of four fatties (the son was over 400 lbs) would come in and hog all 4 of the carts. Invariably, I would get called to the service desk because of some older person who would actually need the was complaining that there werent any carts available. At $2K each cart, it was like pulling teeth to get the home office to give us more carts. Of course, it would help if people who didnt really need them would stay off of them.
