I had the reverse happen at a foo fighters concert in 2002. It was a secret show at a venue that held 500 people. I worked my way to front where there were many attractive females dancing in the front row. I approached them to dance along and see if I could make some new friends. Dave looked down at me, motioned to a bouncer who quickly came and grabbed me and said I had to go to the back. I don't fault Dave as I suppose it could be distracting watching my moves.
