I don't like using public restrooms so I usually go down into my office buildings basement. Nobody is ever down there and I get my own private toilet. No phone service though so I can't browse Era while I shit sadly.
Did we ever get to the bottom of the question of why it matters where you go to the toilet? Surely it's just something we take for granted. At school, at work, at home, in larger supermarkets, at swimming pools, basically everywhere.
I try to not poop at work because I have a bidet at home. If I poop at work, the rest of my shift I feel gross. Not to mention I have a lot of down time at work anyway, so I don't need it as some kind of escape from everyone.
