THIS. It's always someone else's testing procedures, someone's else's hardware... The thing is though, most of the time it is. Tech support at the lower levels especially are used to dealing with people who have bad configurations are are using the products incorrectly. The annoyance comes in when you as a customer narrow a problem down but can't get anyone on the phone who can help you at that level.
