This is a serious question and I'm very curious as to everyone's take on it: What is the difference between the driver who gives out his boss's card and the boss who waits a few weeks and calls the customer himself? The end result is the same. If your customer is happy with you - no problem. But, there are lots of carriers who will promise great service (they've proven that if they have already been in there a few times) at a lower rate. Then once they have bumped you out, they increase their rates. How do you fix this problem?
