I mentioned before that architects don't seem to like signs. I was in a brand new office block last week, looking for the loos. There were labels on the doors themselves to distinguish the ladies from the gents, but nothing you could see side on or from more than a couple of metres. But I had no trouble finding them by instinct, or perhaps through deduction (they are often near the lifts as they both need the central service shaft). Of course the clincher was the cleaning trolley.
