Unfortunately many below average golfers overcompensate by trying to take pride in being "fast players," while scapegoating better players accused as "slow players." It's a form of bad sportsmanship that doesn't get enough attention in the golfing media. It is very disturbing to see the types of distracting tricks they try to use...
Take an example of a par four, where the better player has a longer drive. He waits for the others to hit, as they are away. As soon as they hit they rush up to their ball, whether on the green, bunker or short of the green. When the player with the longest drive finally has his turn to hit, he is often faced with multiple players encircling the green or actually walking around on the putting surface. When he hits, he is the last to arrive on the green. Often some of the other players will begin to putt out of turn, accusing him of being "slow."
Another form of gamesmanship and bad sportsmanship is for the players who have rushed, to walk off the green to the next tee without letting another finish putting. This further creates the false impression that the player left on the green is "slow" when the group behind approaches.
Other rude and unsportsmanlike golfers will simply make a beeline for their ball, no matter where it is in the course of play, hit, then follow their ball to the next shot and so on.
I have spoken directly to such players, telling them not to hit and walk in front of other players, and the common response is "I wasn't in your way," or, "We're just trying to move along."
These players are usually the ones who improve their lies, etc., and try to employ distracting pressure to win a hole or a match. At regular games my club has had for six years, which used to be fun, balls are tossed on the ground to make up the foursomes at random. This precludes being able to arrange one's own pairings. It's a casual club without a membership committee where such conduct could be raised and disciplined.
I would be interested to hear opinions, particularly from golf professionals. We recently had a retired tour pro join the club, who immediately saw through the shenanigans. Naturally, both he and I have been labelled "slow players" because we observe both the rules of golf and etiquette.
