A good looking middle aged male customer walks in to this barber shop and sees it crowded.   He asks the barber "how long" and the barber says 45 minutes.    "I will be back' and the man walks out.   He comes back after an hour and see it less crowded but still no chair vacant   He asks the barber "how long' and the barber says about 30 to 35 minutes.    "I will be back" and the man walks out    He returns in an hour and the shop is not crowded but still no vacant chair.    The man and the barber go through the same routine and the barber says about 20 minutes.    "I will be back" and the man walks out.     Just curious, the barber asks his assistant to follow the man and check where he goes.     The assistant returns in 10 minutes and says "he goes to your house".
