It's worth a try man. But I wouldn't go in swinging bows, I'd start out talking nice and if being nice doesn't work, then you politely ask to speak to a manager and up the tone. It's amazing what a little niceness does.
The only time I will "fluff" is either: some kind of standing water, or a time when I may break a club. Sorry, but it's not worth it to me. Although I did hit my PW on Sunday from right behind a root above ground and put it to 5 feet for a birdie.
Awesome shot I say.
Whenever I golf with my dad I get a cart because he has to use one (hurt his knee not too long ago), plus he walks all day during his job, so on the weekends he wants to relax. If I'm playing alone (or with someone who wants to walk) I'll do it.
