You say “Indonesia. Badminton is part of their national identity. It’s the only sport Indonesia won an Olympic Gold Medal. They also say a prayer before they play according to their religion. Player must wait until his opponent is ready before they serve. Feet of both players must remain in a stationary position until the serve is made. It’s not a fault if you miss a shuttle while serving. The shuttle can not be caught or slung with the racket. A player cannot hole his racket near the net to ward off a downward stoke by his opponent or to interfere with his racket.
