With all the dishonest People in the world trying to take advantage of the rules the People that often suffer are the ones that are trying to be helped in the first place. We often see healthy People parking in handicap parking places while truly handicapped individuals circle the parking lot looking for a spot.
It is a similar situation at Disney World and other theme parks where able bodied guest fake a handicap to achieve front line status. The easiest fake handicap is that of being Autistic, it had gotten so bad that Disney had to discontinue allowing truly Autistic People front line access.
