Does that make you feel like a big man? Massage your ego? Maybe the person working there, shock horror, just needs the money. So what if they don't know everything but who does? Is it really necessary to go out of your way to make their day
that little bit crapper? You don't sound any better than the geeks that go into `that well known computer chain` just to rip the **** out of the staff.

Honestly, do you not have better things to do with your time? If there's one thing that I can't stand is pointless acts such as this.
