Hi everyone, After having watched the Sudirman Cup game between Lindaweni Fanetri against Sindhu, I wondered about a thing that happened during the match. After the interval, the umpire called Lindaweni and told her that she has to put her towel in her bag (as it was still on top of her bag). I've seen this happen before in other matches and tournaments, and I wonder why the umpires are so strict with it. I guess it has a logical reason, but can't think of anything as it still sounds so... trivial to me. Can anyone shed some light to it? Thanks!
