They left him hanging and then blew him off when he requested help. He said something along the lines of, "Is this how you want to treat me." and got an affirmative answer from one of the guys. He then whipped out his business cards and loudly announced that he could hook anyone up with a new kit just like the ones in the display case for less than half of what the price was there.
They kicked him out after everyone took his cards and left the store and banned him.
He was just trying to get some
juice to hold him over.
I'm sure they did not expect to piss him off that much, or that he would act so aggresively, but since I know him real well, it was what i would expect of him. Also, since there was some relationship with him and at least one of the guys there before they ever opened the
shop, that person should have known that blowing him off was something he couldn't let stand.
