I am a intermediate player who plays pick up games in a local club 3-4 days a week. I usually play with other usual players there. There are a few people serve this way: 1) He gets ready to serve, but his hand / fingers keep adjusting the grip, before he settles the grip, he hits the bird. I wanted to point out it was illegal, but since my partner (just a pick up partner), told me to forget it. My partner did not say if it was legal or not, he just did not bother to confront.2) a player picks up the bird from the floor, slowly walks to the serving position, but before his walk stops, or just as soon as he stops, he hits the bird to serve. Couple of times, I did not receive, and told him I wasn't ready. Sometimes, I knew it would happen, so I even give him a quick net shot.3) when a player ready to serve, he look down at the bird, I was waiting, then he suddenly looked behind me like something just happen in the next court, then he serve.I post this here to ask two questions. 1) are they legal? I think 1 & 2 are not, for 3, I just blame myself. 2) like I stated at the beginning, I play with almost the same 20 ppl at that club, I can't, and don't want to confront them, or ignore them. What will you do?At this time, I say "no thank you!" to games that they are in. But I am afraid other 2 guys think I ignore them too.
