West opened 1♥ playing precision (natural 5+, limited to 15 points). East responded 1♠. South overcalled 2♠ natural, west rebid 3♥, and north ended the auction with a jump to 4♠.
As the hand got played out there was a full count on hearts being 6-2 and diamonds being 3-3. West had also played the queen of clubs on the first lead toward dummy. Declarer had a trump coup available if west had essentially x AKQxxx QJx QTx but would go down if west had Jx AKQxxx QJx Qx (ie - if east had psyched 1♠ with xxx xx xxx KTxxx). Declarer wanted to ask west if east has psyched that bid before or psychs often, but didn't want east to be there to hear. This exchange ensued.
South: Could you please leave the table for a moment? (to East)
East: Why?
South: So I can ask your partner a question.
East: I don't think I have to leave, I'm entitled to hear any question you ask just like my partner is. Anyway if you want to call the director and see if he will ask me to leave then that is fine.
South: Never mind.
Questions: Was anyone out of line? Should south not have asked, or should east have left? If anyone had called the director (either before or after the exchange) then what should he have done?
