When I was a kid I was in the school band, and for one or two of our performances at Christmas we actually had to go out of our way to ask the people we were playing for not to smoke during the performances.
AND WE WERE SECONDARY SCHOOL KIDS!!! (11 - 16) I mean for the love of god we were children, and musicians at that, and still adults thought it was fine to smoke in front of us., in enclosed rooms.
