AWS support, for example, tends to be really good about waiving charges for things that are clearly your mistake, like an unused instance that you forgot to turn off for a couple months.

This is an admission that their UX sucks and makes it hard to know what state your account is in and what you're paying for. They waive the fees because a few high profile cases of people paying thousands due to the AWS console being awful would drive a lot of customers away.
