The $100 commission is not the point here; the fact that this guy is giving Guitar Center a terrible reputation is. I'm sure the GC higher-ups would LOVE to see this thread, find that guy, and give him the boot (and possibly sue him, too - who knows if this was the first time he conned money from the company in this way?)
Take it to the extreme, for argument's sake: Say this guy has a scam going wherein he has a network of people who order online, who then report their purchases back to him, and they split the commissions. Say he racks up $250,000 of commissions in a year for online sales for which he was not a party, and pays out $250,000 in cash to various customers for their roles in the scam. What do you think the GC online sales department would have to say about that? Do you think the salesman should be fired, then?
No one ever said anything about threatening to kill the guy. All I'm saying is that GC probably does not want this guy representing their company to customers in this way, and if they knew about it, they would be quite unhappy.
As far as your argument that "big greedy corporations" have "no sense of morals or fair play," I ask you, since when do
two wrongs make a right?
I will skip the Economics 101 lesson and simply say that in any market sector, all companies make a zero economic profit in the long run. All rational people (customers and companies alike) look out for their own interests first, when it comes to money, and this is a GOOD thing - the entire basis of microeconomics depends on this principle. None of us are any more greedy that GC - we try to get the best deals on gear when possible, and every once in awhile, we throw someone a bone if we think it will help us build a positive business relationship, or even just to make ourselves feel better as far as being charitable (e.g. overpaying to support your local mom & pop). In fact, GC offers a lot of helpful services for musicians like clinics in stores, online guitar lessons, a musician match/finder service, etc, and they have low prices for working players, free shipping, price-matching, etc. Explain to me please, how does this make them greedy?
