I currently have my handicap parking permit due to an illness that cannot be physically seen. I attended an event over the weekend at which time I was stopped by an employee and asked why I was parked in handicap. I told her I was disabled and had my parking permit hanging in the car. She then went on to ask what my disability was and that her view of a disability was someone in a wheelchair. I also was not allowed to enter through the handicap entrance because they were out of handicap wristbands. I had to walk around which was very tiresome to me. I was so exhausted that I did not even get to attend the entire event. Is this legal?
