do you guys tip your house-supplied sound guys? i have before, but my current band feels that the soundman is typically making more than we take per guy... so why bother. i can see both sides, but was curious what you guys thought? our best nights are maybe $1200 to the band, but split among 7 guys, and subtracting band-expenses... i might take $120 on a good night. figure the soundman is making similar (and more on the weaker nights).
