The sign reads:

The "Monk Chat" club wants to inform our foreign guests for your own benefit that you are advised to chat with the monk who carries his ID card only because he has passed proper training in Buddhist knowledge and manners. If you encounter any monk who has been impolite or has caused you any trouble, please write his ID card number on a piece of paper and put it in the comment box.

The monk chat club will not be responsible for any trouble that may arise, if you talk to any monk who carries no ID card out side of the specified area.

Thank you for your co-operation.
