Final answer:
In golf, footprints in a sand trap should be smoothed out after the shot, as it is good etiquette and helps maintain fair play for all golfers.
Step-by-step explanation:
Footprints in a sand trap should be smoothed out after the shot. In the game of golf, it is considered good etiquette to rake the sand and smooth any disruptions after playing a shot from a sand trap, also known as a bunker. This ensures that the playing field remains fair for players who might land in the bunker later on. By taking care of the course, golfers show respect for the game, the course, and other players. Not doing so can result in a more difficult and frustrating situation for others.
