At the end of rally in second game at the Swiss Open 2021 XD, this happened: https://www.instagram.com/tv/CMCtFMDp7kr/?igshid=1uf530l2pj5jc The court is in a 4 line judge configuration. It looks like one of the end courts, as there was no live stream available at least on the official channel. What is seen: Baseline line judge signals shuttle landed IN. Blue team wins rally. Red player picks shuttle comes toward net, then gestures for court wiping. All players take drink and towel off. Discussions, lots and lots. Please discuss what to do to resolve this situation properly. There are several aspects here that are related to maintaining focus, and teamwork, and empathy. As an umpire, you cannot enforce sportsmanship, so we leave that for another sub-forum.
