That's a little bit like saying a private club should not be allowed to sell Callaway equipment because not everyone can buy it there.
Callaway (or any equipment company) is going to go where they can sell clubs. If that means they get invited to a private club to demo their product, that's what they are going to do.
As far as I know all of the big name vendors do demo days at pubic and private courses. If you are not a member at a private club when they have a demo day you will just have wait until they have a demo day at a public course. Don't hate on private clubs. My private club has multiple vendors set up their tents on our driving range and it's a great way for the members to compare the latest club technology from one manufacturer to another. We also have demo days where only one vendor will be on site. Our city public courses have the same thing as well as a few semi private courses. There are also golf centers who have indoor and outdoor ranges that have professional fitters on board and every day is a demo day. I get emails every week from these semi private clubs that they are having a vendor like Callaway reps on site and the public is invited. You just have to keep your ears open or just pick up the phone and call and ask when the Callaway rep will be on hand.
@Stumpnavand @CarlT9704 - not my intent to "hate" on the private clubs at all - more power to them. But I can see some benefits to Callaway for opening up demo events even at private clubs. Heck, I can even see how it would benefit the private clubs to have potential new customers get eyes on to their facility.
Callaway employees are manufacturer's reps at Demo Days, all sales are run through the hosting facility. So, the 'facility' determines whatever rules they want to use for the event including pricing. That being said, the facility probably would like to make sales so as long as the members are accomodated fully, the Pro would probably make an appointment for a serious buyer. What he would want to avoid is the guy that shows up at Demo Day for the free range balls or hogs the limited time from his memebership. The people that pay the monthly dues at private clubs rightly feel like they are paying for exclusivity.
Email the pro, express you interest in a fitting and purchase, and ask for an appointment..
