When I play at a competitive level, the games are usually very intense and very few bad habits ever occur, but as soon as I play at recreational club, all of a sudden, it's like I get to see all sort of bad habits/tactics... so... In a game of recreational doubles badminton, what would you consider as the worst habit/tactic possible? or something that your partner does that really annoys you. a) lifts the shuttle when receiving a serve b) bad serve position (eg. standing at the sidelines) c) illegal serves d) serve high like in a singles match e) plays backhand shot when an around the head shot can be played f) plays a mercy shot when it can be hit as a winner g) stays too close to the net at all times h) stays in the front when obviously a defense formation is needed i) doesn't have a clue on what to do in the front court j) backs up when he/she should have been in the front k) lift the shuttle when NOT under pressure L) blame you for not returning a powerful smash when he/she lifts for no reason m) tries to play a fancy shot during cruical moments of the game n) keeps on slowing down the shuttle even after both sides agreed on the shuttle's speed before the game. note: seniors love doing it o) complains about how he/she can not adjust to a plastic shuttle from a feather shuttle or vice versa, when obviously it is his/her own lack of abilities. Note: this is my choice for the worst sportsmanship ever p) last but not least, lying about an obvious line call.
