There is one time when insurance is so popular. What I mean is, out of 10 people you know, maybe 8 or 9 of them are the insurance agent. Even your primary or high school friends who never contacted you for ages will call you up for meet up. I never entertain them. I will only buy the insurance from my friend who i trust. If you are an agent who can trust, you no longer need an insurance advertising since your customer will automatically help you to do the free advertising. From here, you can see the power of a customer. That is why, for those who in the service line, you need to treat your customer well.
