I was assisting at Zumba again tonight when the instructor started to yell "No pictures!" I look over and two teen age girls are taking pictures with a cell phone. The instructor gestures to me and says "the camera"! So I went out to talk to them. By the time I got close, the girls had high-tailed it out of there. I didn't want to chase them down the hall and wasn't quite sure what I'd do or say if I did catch up with them since this issue was a new one on me. I did find out that the gym's official policy is no cameras for privacy reasons so now I know what I can enforce.
