Thanks Scrump!
I'll try the crisp idea next time I'm in!
By the way GUEST,Uncle Arrogance (very inventive)- I have called in the session for a drink twice since. Have been requested by the other players and the organiser to sing which I have refused. Made it plain to all and sundry that the reason is (as Kendall remarked) that I do not wish to be part of them (the offenders). No one is running - no tail - head held high!
I sing 5/6 nights a week so am not hiding from anyone.
I do not know Kendall but have read many of his posts and doubt if he would be classed as a 'runner' either!

By the way, on the original question on this thread - Yes, you were right to leave Shaneo. If they can't show respect then they don't deserve your respect. Respect is earned!
