How Long For A Haircut?

A man popped his head into a Barber's shop and asked "How long before I can get a a haircut?"

The barber had a full shop so said "About two hours".

The man left.

A week later the same man returns and asks the same question. The shop is full again so gets the same answer. The man disappears again.

Another week passes and the same question is asked yet again. He gets a similar answer and disappears.

The barber turns to his friend and says "Hey Bob, do me a favour and follow that man to see where he goes. He keeps asking how long for a haircut, leaves and never comes back."

Shortly after, Bob returns but says nothing.

The barber says "So, where does he go?"

After a pause, Bob says "Your place."
