I don't want to start discussion about what to do with people like that but I would like to present two amusing masterpieces of his:
1)
Our hero plays 3NT, and has something like:
xxx Kx AJx QJx in dummy to:
xx Axx KQxx KTxxx in hand.
The lead is small heart and it's immediately clear that the contract will need some serious help from opponents.
Our hero asks for K of ♥ from dummy and when opponent follow low he also follows and... waits...
After about 1 minute of this impatient opponent asks "it's your turn, you know ?", "Oh, sorry, I took the trick ?". THen he plays clubs and opponents, once in with A♣ tried to cash hearts - fully deserved overtrick :-)
2)
Our hero play in 6♦, hands are something like:
x AKx 9xxx KQJxx in dummy to:
xxx Qx AQTxx Axx in hand
Opponents lead A of ♠ and much to his dismay our hero - having excellent eyesight - saw KJ second in his LHO hand. It seems that there is no hope but not for truly imaginative player.
He ruffs the 2nd spade plays low diamond from dummy and seeing low from RHO exclaimed : "All hope in a finesse!" and banged down the A♦ (!!) of diamonds. Naturally opponent tried to take the trick with K[diaomonds]. Now it was enough to find an explanation for playing diamonds from top again

There was a lot of discussion about those displays in polish community but the fact is this player continues to play
