Thank you for that excellent comment, it really helps me understand the situation better. I too have a disabled sticker and placard, and I make it a point not to use the reserved disabled parking spaces unless I REALLY need to, because there is always someone worse off, whom I would be ashamed to walk past if I took the space. That is why the wife's shameless refusal to move her car when requested struck me so much. What kind of person can do that?
