Greg,
Clearly we come from very different golf ciltures and, despite my pointing out specific examples, both professional and private, you seem to refuse to believe me when I tell you that outside of your bubble, for a great many people that play golf on this planet, your mercenary behaviour is not the norm. It may be what you need to do to survive as a business and keep your financiers happy but it isn't the norm for an overwhelming percentage of golfers. Again, whilst that's fine in a business sense, don't expect a consumer to applaud it simply because it pays your wages.
And if your position is so universally acknowledged without any need to be upfront about it, how come you find yourself having to march people to the car park? Clearly not everyone is as au fait with your policy as you suggest.
Like I said, if you're absolutely upfront about it and make it clear that yours is a conveyor belt operation, fair enough. I imagine that lady that's an absolute beginner won't be booking up, certainly not after she's been grouped in with three scratch golfers but, if she does play, she'll have no one to blame but herself for failing to read the terms and conditions.
