I remember once there were many complaints about a certain brand of bulbs made for cars, with claims that they were too short-lived.

The company sent over their representative to Malta to investigate and he was welcomed at the airport by the local agent. They took a car to the hotel. As soon as they arrived the representative told the agent: "I can return now. There is no need to investigate. How can you expect bulbs to last very long with your bad roads full of potholes?"
