There is a grocery store chain that does that. You get your quarter back when you return it to the cart holder. First, and only time, I wnet to the store I did nto have a quarter but lady coming out let me have her cart for free. I can see why they do it, but it is a pain in the neck. Saves them looking all over parking lots for them, hiring someone to look for them etc. The airports do the same thing. Take care.
