Would anyone have a problem with those who needed the handicapped stall (and when I use the word need that I mean they have NO other option), not waiting in the general line, but standing in front of the handicapped stall. If you are at the front of the line, you may not see the person with a cane or in a wheelchair 6 or more people behind you. This would also allow people who need the handicapped stall for invisible disabilities to indicate that they are waiting for that particular stall. IMHO It just seems a little much to expect disabled people who need the stall to wait their turn in line, then have to wait again, maybe for all of the stalls to empty again, letting people who were behind them in front of them, because they can only use one stall in the bathroom, and the person right before them just went in, thinking "Well, no one else needed it"
