i don't do either. i'm in a different situation where i work with all women, so i keep it as tame as possible. on top of that, my office is small now, and we share a bathroom. it's very public knowledge as to what goes down in there. we have one employee who absolutely destroys the bathroom on occasion, and everyone gets upset. the bathroom is even close to one of our operatories, so if it's bad enough, i can smell the devastation while i work. it's too much.
all that being said, i'm building a new building that should be done at the end of june. as part of this, I have my own office off the beaten path, and I made sure i had my own bathroom in my own office. only my ass will touch that seat moving forward. it can't come soon enough.
