We have unisex toilets at work. They're individual cubicles, each with a washbasin and sanitary bin, and they open directly on to the corridor. Each set of toilets has 2 cubicles with windows that open and 4 that are internal and (allegedly) have an extractor fan.
The first floor is mostly open plan.If anyone has a stinky shit there, the whole of the top floor knows about it.
The ground floor isn't much better. The bogs are opposite reception and the doors to reception are always open. A stinky shit there can knock out anyone who happens to walk into the building.
I will only shit in one of the bogs that has an opening window. I open the windows before I start. I take my cigarette lighter to burn off any methane that hasn't fled through the window by the time I've washed my hands.
I don't want anyone to think I'm the Stinky Shitter!
I feel blessed on any day when I need a crap at work and there are no courses running in the training room opposite my office. There is a lovely big disabled lav off that room, and I regard it as my own personal crapper. It never seems to occur to anyone else to use it, and my friend worked there for 12 years without even knowing it existed. Mind you, she didn't know there was a shower, either.
The facilities manager refuses to buy air freshener on environmental grounds and insists it's not necessary as all the lavs have fans or windows that open.
