Josh,
Two different reasons slow play occurs:
1) The people on the course. Either golf is not their first priority, they don't know how to play fast, or they naturally move at a snail's pace. You can combat this by a) Having the starter re-iterate pace of play expectations; b) Ensure that groups are playing from the correct tees (we all know what sorts of egos golfers have) and have the starter pass on a few basic "tips" of how to play fast c) Having course rangers strictly enforce pace of play and move slow groups, in necessary; and d) Use some sort of timer on the carts (Personal Ranger was the one we used to use - it tells you where you should be on the course i.e. 3rd Tee, 7th Green).
2) Issues with tee times or the course set-up/design. In regards to tee times, simple math will tell you that 7-minute tee times don't work when you are stating a 4.5-hour pace of play. In regards to the course set-up/design, pay attention to where pace of play problems tend to start during a round. The last club I worked at in the industry, we had a par-3 second hole with woods, a stream, and the entrance road surrounding the green, followed by a par-5 third hole, which was the toughest driving hole on the course, with plenty of opportunities to lose a ball, followed by a drivable par-4 fourth hole. Needless to say, these three holes tended to clog up the course each and every day. See if you can target in on a situation like this on your course, or even course set-up issues (i.e. don't cut the pin near the front bunker, shorten the first hole, etc). If you have this sort of an issue, make sure your rangers focus in on these specific holes to help combat the problem.
The only other option is to appeal for bailout money and hire a sniper.
Dale,
In regards to the discount in the bar... what happens when one group holds the rest up?
