One criticism, there's not much mention of the tate of the toilets, a huge oversight in my book. 
Tate?  as in Gallery?
I've seen nothing artisitic in the bogs, although I have left one or two works of art
It's not you is it Lorry? I mean, the person who goes round gratuitously writing filthy stuff on bog walls? No I didn't think so, the identity of the Bog Artist remains a mystery. 
Still, whoever it is can they please desist forthwith. Look I go in there for a dump, not to read about your sexual fanatasies. I'm not interested if you have big hairy balls nor do I want your phone number. Moreover, I most certainly don't appreciate the fact that you have apparently "blown your tanks" on the cubicle wall and then drawn a big arrow to point out this atrocity to all future users of the toilet. Stop it, whoever you are!
