I was doing a gig at a big art show this weekend and one of my friends who I know knows better came in the booth and asked what was going on and if she could play with the turntables (just switched to serato). Luckily I was just able to give her a dirty look and she moved away. But seriously half her friends are musicians and dj's and she plays bass herself. I dont think she would have liked it if I came up and and started playing with the knobs on her bass amp.
