I don't know how combining Bingo with any other activity will affect your tax status. I think your association should run the Bingo games so that you will be under the auspices of
Chapter 849.0931 which makes Bingo legal in HOAs, condos, co-ops, mobile home communities, etc. Under FS 849 you have to pay out all of the money that people pay to play AFTER deducting expenses to run the game (cards, markers, etc.). Any money leftover should then be donated BY THE ASSOCIATION to a charitable, nonprofit, or veterans’ organization which is exempt from federal income tax.
Note that for the association to donate the leftover money (ideally there shouldn't be any) the money would have to belong to the association in the first place. Ergo, the association should run the bingo games.
If you're NOT operating under FS 849 then you're probably in violation of the state's gambling statute.
FS 849 requirements contains language regarding net proceeds, prizes, and business expenses for running the games. Non-bingo related items are not deductible and while you'd need to ask a lawyer to be sure, I don't think food and drink qualifies as a "bingo business expense". The statute seems pretty clear on that.
I'd not have any vending of food and drink anywhere near my FS 849 bingo games, at least not to the point where the comingling of funds might take place. If you choose to do so then that activity would probably subject you to some form of tax liability. Trying to evade that liability by hiding it under your bingo operation is probably a very bad idea.
