Context issue in golf.

Most amateur golfers try to keep the golf etiquette during playing golf. However, there are three big problems on the golf course.
1)Fake other players.
2)Shout in the golf course.
3)Delay of the golf play.
First of all, some amateur golfers tend to fake other players to get the win and look professional. For instance, if somebody loses the golf ball on the golf course, s/he could pretend not to lose the ball by putting the ball on the golf course naturally. Secondly, sometimes amateur golfers have a tendency to shout in the golf course according to their emotion. For example, if someone success putting the golf ball on the hole cup at a time in the difficult situation, s/he might yell because s/he gets so excited. On the contrary, if someone success putting the golf ball on the hole cup in many times in the easy situation, s/he might yell because s/he gets so angry. Lastly, most amateur golfers tend to delay of game progress. There are two reasons for delaying of the game progress. 1)They just focus on their shot or swing. If their swing tempo is very slow, the pace of play cannot help delaying. 2)They try to hit a ball as many as possible. If they hit a ball a lot of times, the pace of play cannot also help delaying. This is why caddies need during playing golf on the golf course.
These three things are big context problems on the golf course. And, it is linked with the lack of the education of golf etiquette.
