People Ask the Strangest Questions

User brudenell at Uclue.com:

Back in Oct. 2009 I asked this question: Seeking size of world market . The question went unanswered. Now I am back instead of looking for facts I seek a reasonable guesstimate (an estimate arrived at by guesswork or conjecture) backed by how you arrived at the number, vcialis 40mg pilule to roughly arrive at a market size.

My question: How many restroom / lavatory / WC stalls are there in the world with a locking door? In many countries stalls exist with no doors. I only wish the number to be units that include doors.

Why in the world would somebody want to know that? My guess is that brudenell has invented a new toilet door locking mechanism and wants an estimate of the global market for an investor pitch.
