I think I wouldn't be concerned about if its beatable or not. I will ask myself if i'm comfortable with that kind of poker atmosphere.

Then I would take a break and eat a spaghetti, say i will pay with my next pot, then leave.

Seriously, and unknown guy dealing, playing and raking in an unknown environment can't smell good for you. Nuts vs 2nd nuts and [censored] like that more than 2 time should make you out of here...
