Call me Steve willya, Dick. You're as bad as that "Mr Shaw" brigade on you-know-where! ;-) Most people are friendly about their photography in our pub session and don't overdo it. They usually banter a bit with us even though they don't necessarily ask permission as such. That's good with me.   Unless you're a professional making a living out of playing I'd take it as a compliment that they want a memento of their night out. Unless you're an illegal immigrant or prison escapee of course!
