Maybe this will help you. I work in a 179 bed facility These people live for bingo 4 times a week. Every time they win they get a bingo ticket we call bingo 3 times then they all have to clear their card and start over they play for 1 hour and collect the tickets. On friday we have what is called bingo ticket exchange. this is like a store set up in the activity room that has deoderant, shampoo, lap blankets stuffed animals knick knacks for their room. jewelry chips cookies bananas all this has been donated so nothing out of pocket. each ticket is worth like 1 dollar deoderant may go for 1 bingo ticket while a lap blanket may go for 10. This is a pretty neat system they enjoy going to bingo to win the ticket so on friday they come up and spend them very wisely. Yes i still have the problem hey she is sitting in my seat or she didn't clear her card but that is life you should try it this way it is less stress and they know they are playing for something but they will not be fighting over money
have a nice day
