well....even EV is better than -EV.
Some people like to play Craps...and if you can play it without the negative expecatation then you are at least not hurting yourself.

the comps that one gets for playing have value also.
Usually the comps that are given out are not much compared to the advantage the casino has over you for the amount of play required.

Obviously if you are somehow playing a coin-toss-ish EV game then this isn't the case.
