If you’re leaving because of ‘pace of play” issues. It’s doing nothing. You can only be as fast as the slowest guy in the group. And if they haven’t caught on by the third hole that “they are slow”, maybe it’s you. Respect is a big part of the game. You show it, and you earn it. I was taught almost from the first time I played, you never turn your back until last guy is done. You don’t have to be on the green, but be close enough to look as if you care.
