I like to use the handicapped bathroom stalls
Why do you feel the need to use the handicap stalls?
The handicap ones provide more space for me to spread out
I can understand if you need more room. The handicap bathrooms are not meant for you and you should not use them. If a handicap bathroom is not available to someone who really needs it, there could be an accident.
It's not like it's against the law or anything. I'm going use the handicap stall as much as I want.
How would you feel if you were in the position of needing to use a handicap stall, and it wasn't available because others who didn't need it were using it? It's best to leave it open for those it's meant for, whenever you can.
