Sometimes small town taxi drivers can be very rude. One taxi driver I had the occasion to travel with was particularly lacking in courtesy, and so I asked for his number. The driver gave me a sardonically smile and said, “Well, if you divide my number by two, three, four, five or six you will find there is always one remaining. But if you divide it by eleven there is no remainder. Do you want to know something more? There aren't no other cabby in this town with a lower number than, who can say the same”, and he drove off, while I stood there completely baffled. What was the man's number?
