Comment 25-30 computers (Score 4, Insightful) 246
I usually say I have 25-30 computers, and ask them to tell me which one has the problem. Reasoning that they called me and must be able to know which unit it is. They will either be confused and pass me to the "next support level" or say it doesn't matter which unit I log in to. At that point I insist they tell me which unit it is. By this time they usually use some foul language and/or simply hang up. Mission accomplished.
