As I was shopping for a party outfit a few days ago, I checked out Plato's Closet, which is great for getting stuff that I don't intend to wear a lot for cheap.
There was a line at the fitting rooms, however, out of three available stalls, only two were in use. The third one was empty.
Knowing that the doors lock when pulled closed, I assumed it was an oversight and asked one of the folks working the floor to unlock it, in view of all the people waiting.
The answer: "This is a handicapped fitting room, and we reserve it for handicapped customers only."
Which would have made sense if there was at least a single handicapped person in the store who could have potentially needed the room before any of us already waiting in line.
