Playing before last trick is quitted.
Declarer (South) is a few tricks into the play. West leads a small Heart, dummy plays, East plays the King and Declarer plays the 8. (East winning the trick). Declarer is thinking (even though she has not won the trick) and is holding her card face up. West, Dummy and East have turned their cards face down. East now immediately plays to the next trick and Declarer says, sorry I'm thinking and haven't quitted my trick yet; You shouldn't have played that card yet. East says (rather aggressively) OF COURSE I CAN, I won the last trick. No you shouldn't says declarer. There is quite commotion! Declarer is upset, East is arguing quite loudly, and as TD I go to the table without being called.
Can I help I say? East says CAN YOU TELL THIS PERSON SHE DOESN'T KNOW WHAT SHE'S TALKING ABOUT.
I warn East about his aggressive manner being unacceptable.
I say you should have waited until the trick was quitted. RUBBISH he says.
Now I'm dealing with Bad Behaviour @ Bridge; and warn him as such and suggests he apologises.
Apart from the BB@B, which he later apologised to Declarer, again loud OK I APOLOGISE.
Can you please advise me where I can find the correct procedure for Play to the next trick. Law 66A describes Inspection of the Current Trick. Law 65A describes the Completed Trick.
