NEVER take a book or other assorted device which holds your attention while going to the toilet. I just went in with my laptop and didn' t realise someone who shall not be named and shamed had left the cover up. I will suffice to say that not only does it hurt like heck you also have the added injustice of your hair (if long) being partially submerged and having to be rewashed at 8:30 at night. You may also get stuck until you deem it necessary to use your hands. And your laptop gets wedged into the comfortable crevices of your face. Okay I think I have made my point. Please please please check to make sure the cover is down before you sit on the toilet seat. The metal is cold and slippery.
