Respect
It is not uncommon for bingo players to become upset and irritated when they hear results they do not like. It also isn't uncommon for the players to blame the caller and engage in disrespectful behavior towards him, such as calling him names or groaning loudly. Show respect and common courtesy towards bingo callers, as they exert absolutely no control or influence over the winning numbers. The only time it is acceptable to make a comment is when the caller is simply inaudible or speaking too rapidly and you cannot understand him.
Stay Quiet
Many people concentrate very deeply on bingo, especially during the calling out of numbers. Show respect for the other callers by staying quiet for the entire game. Abstain from chatting with your friends or people sitting near you. Turn your cell phone off or keep it on "vibrate." Some players may be hard of hearing and if you talk over the numbers you may cause someone to miss out on winning.
Personality
Show your personable side at bingo games. After all, bingo is an interactive activity that involves being around a lot of other people. Bingo is not solely a game for winning -- it can be a fun and rewarding experience that helps you to make a lot of new friends that have similar interests to you, as well.
Calling "Bingo"
If you are so lucky that you have winning numbers, make sure to say "bingo" in a clear and loud manner. If you mumble "bingo," people may not hear you. Also, if you are going to call out "bingo," double check to make sure you really have it. If you call out bingo falsely, you waste time and risk annoying other people.
Seating
If you notice that regular bingo players often take the exact same seats every week, show a little bit of respect and try to stay away from those spots, if possible. This is especially important if the other person considers it to be her "lucky" seat. Also, if you place your things (bags, cell phone, etc.) all over a seat you are not using, make sure to take everything off if the hall becomes crowded.
Tickets
It sometimes happens that you have to exit the bingo hall a little earlier than expected. Whether you have a headache or your friend has called you with a problem, you may have to leave before the game ends. If this happens, make sure to exit the hall quietly and gracefully. If possible, offer any tickets that you didn't use to fellow players. A little generosity can go a long way.
Graciousness
Be gracious. If another person wins, do not act visibly upset. It is not a crime for someone else to win. Try to be happy for the other person, and remember that it is only a game. Do not be a sore loser that ruins the fun for everyone. Try to keep the atmosphere fun and upbeat.
