Jerks like that take the fun out of the game . Not all Champs are like that . Those who are , are red tee Champions . They got to Champion by playing from the red tees in their country clubs . They will continue to quit and bail until they reach saturation then it wont matter . So dont let it get to you . Play well and have fun
Maybe that's the point, the person he's talking about doesn't play red tee. So he's "cheating" getting his average from his own tees while others are playing from shorter ones within the rules?
Quitting doesn't help you tier up faster, the more rounds that count the quicker to saturation and losing the bad scores. Playing red tee is the way to go if average and tier is what you care about.
I suppose it is a little bit of a pain having to wait a couple of minutes for your game to finish but that's the only way it affects you, hardly a big deal.
