You're at a Country Club, not some Muni so you prolly won't get too many rude fwd guys. What others have said, just be friendly and mindful of the golfers. One thing a girl did for us yesterday which was really great and we tipped her well was we were on the green and she had filled up 4 cups of ice and put them in our carts.
We didn't need anything at this time but she just told us that she did it and she'll see us in a few holes. Really went over well
