In 1990, Congress passed the Americans with Disabilities Act. One of the requirements of the law is that businesses and other public institutions had to set aside a certain number of parking places for people with physical disabilities.
Well, I know people who keep a handicap placard in their glove compartment and pull it out whenever they can't find a parking place close to the venue they want to attend. If these folks have handicaps, they are mental, not physical.
Evidently, the strategy is to get a doctor to issue a temporary permit because they are doing some form of rehab, and then use the permit permanently.
Whenever you see a fully mobile person parking in a handicap parking space, you have my permission to give them a shame on you look.
