I have also used handicapped stalls when taking my children in with me. I never for one minute thought that these stalls were "reserved" for handicap only. It is not like a parking spot. Youre not going to get fined if you take a seat. If there is a line, whoever is next takes the next available spot and if that happens to be a handicap stall thats what you get. Of course, I wouldnt use it if there was other stalls available and didnt have a need. Am I wrong on the rules?
No, you're not wrong at all. Legally and morally those stalls are available to anybody. They aren't like parking spaces that are reserved specifically for handcapped people. Obviously if you see someone who needs it, you should leave it for them. But that doesn't mean only handicapped people can use them.
