Slab covered most of this but for me if anyone at a club treated me like dirt it would leave a sour taste, no matter the quality of the course. It is about the whole experience, not just one aspect. I would totally agree that the course is the reason to go to any club, the clubhouse is secondary by a long way, but once there I expect to be treated with courtesy and a smile. Having read your posts previously I am sure you must have played at Turnberry. By crikey they have got it right on and off the course and that makes you feel special for every moment you are there, not just when you are playing the 18 holes.
i get what you are saying, but the club house etc, are way down the list of why i go to a course.
For instance, Skibo you get treated like a king. from the moment you arrive, a guy takes your clubs and makes sure they are ready on the range /putting green then first tee. Locker with your name on and goody bag, bag tag again with your name one. a few refreshment huts out on the course where everything is free. when you finish a guy takes your clubs and shoes and cleans them and takes them to your car. Food and wine and service are excellent, locker room is like very classy and everything you would need there is layed out for you. But at the end of the day, i don't think the course is that great TBH apart from the front 9 of course, so would not rush back TBH
