Picture 133: bathroom

this bathroom really confuses me. it is located in my office building. and as you can see, there is an extra chair in it. as you can also probably tell, it is a one-seater toilet. WHY is there another chair in there? i realize there is a stereotype with women always going the bathroom together, but this time i think we've gone a little too far. i don't need my girlfriend sitting right next to me as i do my business so we can catching up on our gabbing. the next stall away is one thing - but this is just ridiculous.
