yes - minus 10 for tuning up loudly while someone else is performing, minus 5 for not being ready if turns go round the room and having to re tune - although once was accompanied in a session by Martin Carthy - I think I can forgive him any amount of tuning. I thought it was so nice he joined in with us mortals.

I think food and free beer is less important than a warm welcome from both landlord and locals. Making sure the TV/ juke box / speakers are off if session expected.

Any self penned tuned in the category of teenage angst - whatever age the singer.

Eating crisps.
Oh dear - the list goes on.
