This explains alot...
 

My husband and I went to the first Good Golf School class we could as soon
as we moved here so we would be sure to understand all aspects of golfing
in the villages. One of the things discussed was the importance of maintaining the quality of the courses by repairing divots and ball marks. Explaining the proper use of the sand and the divot tool for fixing ball marks on the green. Our home club also stresses the same thing, so for us this was
second nature. After reading all these comments concerning pace of play I
now understand why there is such a lack of care to the ground both in the fairways and on the greens. Apparently players of all skill levels are too
afraid of slowing things down to leave the course in as good a shape if not better than they found it. This is a shame as over time this will effect the
quality of play for all of us. I will continue to do my part as I always want
those behind me to have as good a time as I always do on these beautiful
courses we are so fortunate to be able to play free for life.

I disagree. Most faster players I have played with are more conscientious about leaving things better than you found them than the slower folks. It does not take additional time to rake, fix ball marks and fill divots. The thing is you have to think a little bit and do the housekeeping while others in the group are carrying on with their game.
It ain't rocket science. Just common sense. Play on....
