Be open minded but critical. Krav Maga isn't MMA, so if they claim to teach it - ask who they learned it from. If they can name someone that you can check up, no worries. And if you decide to train there and there's some are hard asses, try befriending them so u let them know you want to learn from them, not compete with them.
