Bingo tipping?

Thinking of playing bingo while in Laughlin and Las Vegas.

I'm not a bingo player but thought it might be fun for a change.

If you do win is there protocol in having to tip when they bring you the money?

Couple bucks if you win a smaller game by yourself. Maybe 2-3% on the bigger games. More if they help you out with things before the games start. Just like every where else, better service equals a bigger tip.
