There's usually always a book or magazine in the bathroom. Sometimes I just go in there to do my business, other times I make the mistake of picking up said magazine or book. I suppose it's not so bad if it's a mag, but if it's a book, and a good one I can end up spending more than an hour in the bathroom.
Please note, I don't spend over an hour in there because that's how long it takes to piss, crap, whatever, but because of the book. The Nasty usually takes less than a few minutes. I stay in the bathroom because it's quiet and nobody can bug me while I'm in there.
