There is No excuse for parking so terribly. And those that take up two spaces deserve everything that is heaped upon their vehicles. My brother hocks up nasty stuff and splatters their windshields if they park like an idiot, his way of dealing with them.
I have had to use handicapped parking since the mid 80's. I walk with canes due to a virus which destroyed my legs and balance. I have a stiff gait at times and honestly in the vein of House there are times when I consider getting up and wonder if what I am getting up for is worth the pain it's going to cause me with the steps.
Many times over the years I would pull into a handicapped spot and be preparing to get out of the car and place my handicapped hang tag and have people just glaring at me because I was in my teens/early 20's. I would open the door, get out and stand up and the looks of I could kill you, your disgusting shooting my was were awful at times. Then I would bend down and remove my crutches or canes, steady myself and close the door and walk off with the die go to hell looks going to I'm a duh boy look!
I had one lady at Walmart, she would be a Karen in today's terms just stop at the back of my vehicle when I pulled in the handicapped spot. She was coming out and stopped and was just absolutely glaring at me with an awful mean look on her face. I went through my process, hang tag, open door swing legs out and stood up, more disdain from her and she was about to tear into me, actually had opened her mouth to start fussing at me and I removed two walking canes, hit the lock button and closed the door. She just stood there, mouth hanging open and as I went by I said don't worry I just walk this way and use these canes for sh*&s and giggles and walked right on by her. She just stood there mouth hanging open, saying nothing as I went into the store.
