Have you ever had to explain to a customer that 'Hosting' and the domain name 'registration' are two seperate things. And that one does not automatically come with the other?

This guy paid for 3 years of hosting thinking he had been reserving his domain name for that long. Then he gets mad at us for not calling him and telling him that he only has the hosting. But trying to explain that just getting 'hosting' is a VERY common thing, was extremely difficult.
