Delay of game.

A tough lesson learned tonight...Never let a player's turn last  longer than one minute and here is why:
Having dined in divine excess on local seafood and IPA,  we had an idea of a hot game Shanghai to end our good day.
I was proud to have led the first 6 rounds with 10 points total.  My Son, Sam, was second with 90 points, and my smart ass husband, John,  was dead last with 390 points.  During the last round, my hand looked pat; I only needed a nine of spades to set my opponents and I would proudly post my picture on this blog.
Then John began his turn and took so long I felt compelled to count down from 60.  At zero, I told him his turn is over.  He then took another several seconds to rearrange his hand and went out.
He set me with 120 points making Sam the winner!
Before we play again, John has to sign a form agreeing not to take any longer (in any given turn) than 30 seconds.   
If you play Shanghai with a player who takes a turn beyond a reasonable amount of time, take my advice:  Get everyone in agreement to disallow such blatant delay of game methods.  Who knows?  It could be you left holding the cards!
