Know when it's your turn and be ready to hit. It is customary for the person who took the fewest strokes on the previous hole to tee off first on the next hole. That mean's you're first to hit on the tee. Then, after everyone's ball is in play, the player whose ball is furthest from the hole is expected to play next. Be ready to play your shot when it's your turn.
Slow play is one of the most annoying problems everyone in golf fights.
Don't slow down play by dilly-dallying to your ball. Be ready to play when it's your turn. That means if you're riding a cart and you must keep the carts on paths, take more than one club with you. Take a handful. And keep an extra ball in your pocket.
