I'm a tall girl. Not an amazon (wish!) but a healthy 5'9.5". So I like the handicapped toilet better than the regular toilets. I feel like I am sitting on a regular chair, rather than a child's seat. Much easier to get up afterwards.
Once, about five years ago, I went to the bathroom at work. Stopped in a public hallway one on the way to a thyroid needle in another building. Walked straight back to the handicapped stall and got situated. All of a sudden I heard someone speak. "It's ok Mom, just try to hold it. The stall is occupied. I am sure they will be out soon. Sorry for your wait." I looked down through the gap under the bathroom door and saw wheels. I was mortified.
I quickly attended to my business, all the while sweating and stressing. Not only was I an able bodied, ambulatory individual, I also had my doctor's coat on. I flushed, got dressed, and decided no way in heck could I walk out wearing that coat. I took it off, rolled it up, and stuffed it underneath my armpit. Took a deep breath, opened the door, and muttered my apologies as I escaped the bathroom to my needle.
I am still guilty of using the handicapped stall in restaurants, but not until after I have cased the area for those who might need it for reasons other than comfort. I have not since used the handicapped stall at my hospital, despite never having seen another wheelchair in that particular bathroom in the last five years.
