Yeah, that was kind of what we were doing. We didn't go off as bad. I'll do that sometimes if I visit a Best Buy (extremely rare).
They often have tech guys asking if they can help you when they clearly don't know what they are doing. I created a litmus test for them.
I'll ask them "How much does the hard drive weigh when it is full?". If they try to give me some B.S. answer I know they can't possibly help me with anything. If they laugh and get the joke then I give them the benefit of the doubt.
