Typhoon At our place the pro makes a cut of what the shop sells so he's incentivized to carry stuff people want and get them to buy it.
He doesn't carry a lot of clubs, but we have demo days and he'll order TM, Cally, Titleist or Tour Edge stuff. He gave up trying to deal with Ping.
I think he does a good job trying different brands of shirts and sweatshirts that are less expensive than Footjoy, but still nice stuff. Every year he gets some nice sweatershirts from Ahead that even my girls like.
Many of us try to support the shop to some extent. Unless I have tons of pro shop credit I don't buy balls there, but I do get clothes and a demo club every so often. The salary the pro is paid isn't that great, but I think he makes up for it with the shop.
