Sometimes what I do is stop in a loading zone if a store employee is present and they help her with a motorized scooter. Then I go get the handicapped spot. This gives me two chances at being harassed. Someone actually said - if you can do that, why take a handicapped spot, are you lazy? I say that when my mom comes out in a scooter, she needs the extra space to negotiate the scooter.
Again, tell me, why do I do I have to justify myself when I am doing the right things for the right reasons in a legal way.
I swear, if that video ever showed up on a "people behaving badly" website, I would create my own website "Assholes without integrity enough to find out the whole story" and let them eat their words/videos.
