I would guess that the casino is a relatively cheap space that can do entertainment and conferences and food, and it's not being chosen for the gambling aspects
It's at a casino because it's near our facility, has conference rooms, event spaces, entertainment, and the weather doesn't matter.
Sometimes some people sit at a table and play while hanging out and that's fine. But it's not really about drinking or gambling. Just having a little fun together and getting to know each other and our +1s on a more personal level.
