In the World Series of Mahjong in Macao (in which I acted as head judge), we supply mahjong rulers to the players. In the first year, many players forgot and subsequently lost their rulers. In the second year, the judges took special care to remind the players to take their rulers when they leave the table, but still one or two were lost.
I'm sorry that I can't help Martin here, but a suggestion to all those who are bringing your prized rulers to any tournament: label (preferably engrave) the ruler with your name! Or even tie the ruler to your pants with a long piece of string. Unless it's a cheap $2 piece you don't mind losing, don't count on your own memory for ruler retrieval!
