In the original 'Trainspotting' film we were introduced to what was apparently the 'worst toilet in Scotland'.
The scene is one of those iconic moments in cinema along with the "Do you feel lucky, punk?" bit in Dirty Harry, Jack Nicholson coming through the door with an axe saying "Here's Johnny!", and Anne Hathaway getting her glorious thrupenny bits out in 'Love and other drugs'.
OK, so we all have different things that stick in the memory.....
The Trainspotting scene however, does make me thankful that I've never come across a toilet in a state remotely as bad as that, but that's probably because I've never attended a music festival.
I admit to being a bit fussy about the facilities I'll entrust my bottom to, which can be a problem in the workplace where so many people seem to have sprinkler attachments on their arseholes, think flushing is optional, and have no idea how to use a toilet brush.
On a list of things I enjoy doing, running between every gents around the site trying to find a lavatory that is sanitary enough, with an increasing sense of panic because I'm about to give birth is pretty near the bottom; somewhere between having surgery and going to weddings.
It makes me wonder if people who leave toilets in such a vile state behave the same way at home.
I expect the majority do not, but when they're at work they somehow get the attitude of "Why should I clean that when someone else is paid to do it?", and I find that frankly appalling.
Even if cleaning toilets is part of your job, surely nobody wants to walk into a cubicle - mop and bucket in hand - to be confronted by the aftermath of someone's big night out featuring ten pints of Guinness and a dodgy chicken vindaloo.
On the back of the cubicle doors at work there is a sign that says 'Please leave this facility in the state you expect to find it', but I can't help thinking that replacing 'expect' with 'like' would be a considerable improvement, because expectations can often be pretty low.
While they're at it, they could also add an instruction sheet for how to use a bog brush and a small pamphlet entitled 'Hygiene - A beginners guide to moral obligations'.
Please wash your hands.
