The job of the Bingo Spotter (or runner as they are often known as) is to confirm a player's bingo as authentic, and to communicate with the Bingo Caller. The bingo spotter's responsibilities include collecting the cards of those players who have yelled "BINGO!" and ferrying them to the caller to verify the win.
You'd better do your bingo daubing correctly or you'll be in trouble! If the card is found not to be a winner, the card is returned to the player and the game resumes.
Often in bingo, the spotter's job also includes couriering the winnings from the Bingo Cashier and delivering those winnings to the lucky player. That sounds like a great job to me! I wonder what the benefits package is?
In conclusion, a bingo spotter is a cross between a tennis ball runner and a lottery ticket analyzer. One thing is for sure... if the bingo spotter is coming over to you, chances are you've got a bingo and have just won some money!
