You have some of the best people on the scene but we also have some of the worst. We have some of the friendliest but also some of the nastiest. The scene has always had every element of life. It has people you want to talk to and associate with, it has people you are wary of and people you want to avoid.
It has more than its fair share of gossips, tittle tattlers, grasses and n'er do wells, thieves and whatever else folk in everyday life get up to. The scene of old always had an edge. You stood your ground and gave back what you took.
If you experience unpleasantness go somewhere else, it will be their loss. Not everywhere is like the venue in the Op, there are some excellent venues with excellent people running them and attending them.
