Some asks you to stop taking photos of their children and you don't.

Rude rude rude.

I think you got off very lucky, I wouldn't have been suprised to hear of someone doing what you did getting a smack by one of the parents (Which would have been wrong, I'm not saying you deserved a punch so don't go there!)

I know what you said, but I heard "It's OK I'm a pro, I'm exempt from being polite and understanding others feelings."

Ah sod it, If I'd have been there with my kids, it would have been me giving you a smack and I'd be prepared for the consequences. I think I'd get a few chears from the crowd for clocking you upside the head (5'3" slight built mom).
