It is a small village. A main road goes from north to south. The village is surrounded by woods. At the northern end of the road there is a saloon with barber named N. He is having a very bad hair style, bushy and shabby. At the southern end of the road there is a saloon with barber named S. His hair style is very good, neat and nice. The village has only these two saloons. N is always busy with so many customers whereas S is having only one or two customers , even though his hair style is excellent. Why this anamoly?
