1/ Air conditioning DOES work..... my local pub has it, no cloud of smoke (unless the coal fire is on.....it sucks the smoke from the chimney and fills the pub!)

2/ Smoke is HEAVIER than air, so does not drift upwards!

I have been to a couple of non smoking folk nights, the atmosphere was as missing as the smoke was!
The place was full of bank managers and teachers who would'nt know a wild rover if he popped up in their porridge.

How about banning Guinness and blokes with ponytails from folk nights?

Oh!.... if your clothes stink, try washing them..... It works
