If I see a handicapped person or someone (Like with a baby or a child...you try taking a 2 yr old with you into a normal stall lol) who needs to use the larger stall, I'll gladly keep it open for them and not take it, even if it is the only one open. If for some reason someone who needs it is kept waiting for me though, I'll apologise.

What I get mad at is people who cut in line AHEAD of handicapped people and then use the handicapped stall when others were open just because it was the closest one (I have seen this happen)
