Is there a purpose to this? Or is your aim to make another human feel miserable and quit his job too, for no good reason I can fathom?
Perhaps your righteousness would be better utilized for a situation where there are actual victims and actual harm, rather than attempting to victimize someone who in all likelihood may simply be working at a job that they were lucky enough to find and hold onto so they could provide for their family.
Keep in mind that people might just do the same kind of thing to you, you being a BBY smurf, because they might get kicks out of showing you how stupid you are and that you don't know anything and are selling junk to idiot consumers who don't know any better. Or, in reality, maybe you simply try to do a good job at a position that you have some pride in regardless of what else you might envision for your future. Perhaps the Monster rep is in a similar boat, and perhaps you shouldn't be so quick to judge them in an effort to make them have so miserable a day that they would want to quit. Seems pretty callous to me.
I don't see people living on the streets because they spent the last of their money on boutique cabling. You know as well as I do that BBY doesn't make their money selling TVs. It's all the ancillary high margin junk like Monster that keeps YOUR paycheck rolling in.
If people didn't want to shell out money for deluxe junk, we wouldn't HAVE an economy.
There are things in the world worth getting upset about. Sometimes a little perspective on what those things really are is warranted.
