Let me just make one thing clear here, I'm not excusing this guy's actions - by all accounts he behaved like a prize tit and the BA crew were right to leave, but some of the comments on here were frankly poisonous.
Lagos may be a nightmare route, and some of the people may be rude and boorish, but that doesn't give us the right to tar an entire country full of people with that brush, and we should at least lead by example. That's not PC, it's just common courtesy.
