Don't know what it says, but I know people who've signed contracts expecting the usual behaviour. I know a contract that promised action based on change requests within x business days, oops, the new customer sent 2000 change requests in a few months, more than the total of all older customers had sent in in years. Surprise!

You may have heard the story about the Colo/ISP that signed up a large new customer (you know the name) with 95th percentile pricing for IP traffic and unlimited power to the cage? The ISP signed a contract that said 95th percentile pricing and expected the usual usage curve, the customer made sure the curve was a very different one. And used (much)_more power in the cage than the ISP had ever seen, too.
