I don't think your in any trouble. A passport should be the most valid form of ID. If your of age to drink or go to the bar id be talking rogue people who manage the club. I'd be more offended than anything because I've been into the bar smashed and they never did anything to me. Because that's bs if they said your I'd isn't proof as a passport.
Who cares... Yea maybe he should have let you in, but you should also have multiple forms of ID on you regardless. I honestly find it sad that you're going to such lengths because you weren't allowed to enter a club. Seriously... u mad much?
