A friend of mine-- a somewhat rabid free speech advocate-- used to break state at all restaurants... actually, he still does. If we went for Chinese, he'd ask the waiter "Which is your best pizza?" or if we were at a pizza place, he'd as "How spicy is your Kun Pao chicken?" and stuff like that.
Naturally, his intention was to "break the script" most people have running.
Sometimes the results were pretty funny...
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.
