agree with the guy who said dont touch my clubs...
1-my clubs are clean at the end of the round, because a clean clubface creates more spin. you want to clean my clubs, do it at the range where i need it.
the club wipedown is a service created by clueless, non golf management and enjoyed by clueless, often high handicap golfers, many of whom use cart bags, carry 100+ golf balls, and often my favorite accessory--the cooler/6 pack
2-i HATE the "you never touch your clubs" service offering--i carry enough balls to get around the course one time, and only the stuff i'll need that day (sunsreen, umbrella, winter gloves) because i grew up carrying my own bag, do it 5-6 times/year, and dont want caddies carrying any more of my junk than they absolutely have to. i need to reload before my bag is snatched away and buried under Al Czervik's travel cover.
i also hate looking around for my bag while some schmo has lost it/sent it to the Fazio course instead of the Hills course/stopped to chat with the cart girl. I usually have 20 min to warm up ('cause i planned to have 45 min and was late leaving the office), and i like hitting balls before i play.
having said that, the guy doing the job didnt make these stupid service decisions, the management did. so i always offer a few dollars and hand the guy my trash or say thanks, but the clubs stay with me.
