On a recent Rotterdam TA there was a group of mojong players who "reserved " 3 Crows Nest tables every morning but didn't begin play until after lunch. After a day or two, people began to move their briefcases and sit at the tables. The players found their tables open after 1pm. It all worked out...maybe they got the message. One thing we like about HAL is the abundance of places to sit by a window on many of the decks...and play a game or just be. There are available tables for everyone. Being considerate of others is the key.
