An interesting thing happened to me today. Well, I say interesting but really I mean uncomfortable. We've all used public toilets at some stage in our lives and in particular most will have used toilets in a work environment. I have used one many times at work, which comes as no surprise. However, today was a new experience. I'm sure most people are familiar with the warm toilet seat. The sign that someone else sat there very recently doing the same thing you are about to do. On a cold day the warm toilet seat is actually a comfort.
