After having foot surgery, and being on crutches for 6 weeks, I too agree with the handicap accessible stall plea. Remember that it normally takes a bit of extra time to get situated when you NEED the handicap accessible stall, so what may normally only take people a few seconds can take those who are in wheelchairs or on crutches a lot longer to accomplish.
That said, I will say that most of the other stalls are oftentimes extremely small, and can make things like cleaning and changing clothes very interesting.
