There are almost no such shops near many large badminton halls!
People who can play in badminton hall for a long time generally have a set of professional equipment, which must be prepared before playing. Generally, I like to go out and buy high-end goods in large specialty stores. I usually go less, occasionally a few times, or a lazy person like me will rent a racket on the court and don't need to buy it at all. Even if I did, there were some in the stadium. So there is no advantage in driving near the arena.
It would be better to go to a place where shopping is concentrated and sports brands are monopolized. To make these things look high-end, how many high-end consumer groups patronize and sell professional equipment.
