EXACTLY!!! So what if they're using all the bandwidth they're paying for? A paying customer is a paying customer.
I have a couple sites that hit their bandwidth limit each month, mostly due to links from Google images. If it becomes a problem, I just go in and edit my package. That's me. Your customer might have a different budget, a different approach, or different circumstances.
