You and your team-mates should make sure you are all up to date about team rules. There are some teams who look for an excuse to call a foul on you. Make sure you all know not to talk to the players at the table. Don't tell them the score when they're in a game. Mark the pocket. Watch your opponent for possible fouls.
Just a few of the little things that some teams watch for. While most of the players out there will treat you with respect and the utmost sportsmanship, some people just can't play without some kind of controversy. You may go 4-5 years and never run into one of these people, but if you do, don't let them ruin your trip. It is awesome to get to play someone from another country who maybe speaks no English at all, {although it does create some challenges}. Just have fun and try to make some new friends. Good luck, Sam
