Yes, agreed Cap'n. A well-run club would not IMO tolerate rudeness in the form of people talking while someone is performing. I expect that when doing a pub gig, but when in a folk club I expect people to do me the coutesy of listening to me while I am performing, just as I would do for someone else. Most clubs have time before the start of the performance, an interval and afterwards where people can socialise. I would not want to go to a club where they treat performers with such disrespect.
