A pair of San Francisco club promoters fed up with car burglaries are taking matters into their own hands to protect their neighborhood.

DNA Lounge show promoters are tired of hearing about smash and grabs in the South of Market neighborhood. In response, the promoters have expanded their security plan at the lounge to include the neighborhood.

"I started seeing a dip in the numbers," promoter David King said of the car burglaries affecting show attendance. "Started polling people and they said it's not worth paying $100 to get a window repaired."

After thieves targeted club staff, performers and guests, the promoters chipped in to hire security guard Jonathan Yancey.

On Monday night Yancey was seen roaming the neighborhood and introducing himself to neighbors and club guests.

After months of the one-man patrol, promoters believe it is helping as guests are talking about the shows and not crime.

"It's a lot of money," promoter Cash Recanzone said. "Someone is just trying to have a good night and not have to deal with that."
