Good point and one that often gets overlooked is the honesty of the scene that firstimers don't understand, your bag,coat whatever is safe left unattended,I have personally only seen one thing go missing at a Northern night, a coat with the car keys in the pocket,a full scale search entailed with everyone getting wound up at such a thing happening.The coats were hung in a communal area, turned out my mate, not a regular at the venue had left early , had the same coat at home and thinking he had worn it on the night just put it on and walked home,all was resolved next morning to everyones satisfaction ,honest mistake albiet a stupid one.
