Most golfers have their own set and do not prefer to play with hired sets, unless travelling; so I did not include that cost. But if you aren't carrying your own set then you certainly have to rent the set. Food obviously you have to pay. If I summarize then Green Fee, steam & sauna (if available) are free and you need to pay for rest of the things. So the figure quoted by you for 2-5K (5K if one has to hire a set and have lunch/brunch as well) is right.So it's about 2-5k per game, irrespective of which credit card you use.
You pay for clubs, caddie and cart
And there's free sauna and meal?
