I will always choose the handicap stall because I like the space between myself and the next stall. It seems like the US bathroom system encourages games of battle shits and I’m not willing to play. I’ve only had one instance where I walked out and a person who actually needed it was waiting. I felt terrible, but it was only once out of hundreds. Does anyone else do this?
Yes, for my own physical needs.
The default stall is frequently so small that I tend to get my back twisted or smacking a knee on the bowel trying to navigate the inward opening door that almost hits the toilet in a stall barely wider than my shoulders. I’m not even a big person, extremely average. But normal stalls in the US are built like airplane seats.
Work stalls are a little bigger than businesses so I use the regular ones there.
So yes, if the normal stall is tiny I use the big one and that is generally the case. In all my decades I only held up someone who needed it once, but was in there because the other stalls were taken.
