How Many Beers Is Too Much On A Date?

I went out with someone, and he had 3 beers for dinner. He was fine and didn't act any differently than if he had had no beers. He drove me home safely. There is alcoholism in my family, so I'm wondering how much is too much? When is it time to say something? I don't drink but I don't know anyone who doesn't drink.
