We Bridge play casually on BBO. We always invite a 4th player to join our table. Often the 4th player who joins our table will suddenly leave, sometimes half way through a hand! Surely a few words in the chat line saying ‘this will be my last hand’ is just courteous good Bridge etiquette and shows respect for other players. If someone was invited to play at your home they wouldn’t just get up and leave without saying anything, they certainly wouldn’t be invited again if they did! Players need to play courteously as they would if not playing online, just leaving a table with no warning I find downright rude. I would be interested to hear other players views on this issue. Sally
