Four partners opened a petrol pump on the first floor of a building, but received no customers because of its illogical location. They then opened a restaurant in the same space without removing signs for the petrol pump, also receiving no customers. The partners started a taxi service but attracted no passengers because they improperly seated themselves, two in front and two in back. When their taxi broke down, they tried pushing it but made no progress because two pushed from the front and two from the back without coordination. The document conveys that without applying common sense, businesses are unlikely to succeed regardless of the owners or type of business.
