Agree with it all @VicPark.
We have a good setup here at my office. I work on the top floor with two other colleagues (male) and the toilet on our floor is a full bathroom (has a shower and everything). This is known is the 'executive washroom' and there is a strict no-poop rule for this facility.
I love being able to use a toilet that doesn't stink, have poo crumbs or claw marks in the bowl!
There is a dedicated male & female bathroom downstairs, so the guys poop down there
For the record, I do not poop at work. I just can't. My body has trained itself not to need to go in business hours.
One other I'll add - if you're one of those people who likes to use a paper towel to open the bathroom door (as in not wanting to touch the handle) - dispose of the paper towel thoughtfully, don't just drop it on the ground (I worked in a large office at one stage and some mystery woman would just leave the paper towel on the ground).
