Think there’s no such thing as a free lunch? Think again.

Hundreds of federal employees braved the cold Thursday and enjoyed a free meal courtesy of GovLoop, the social media Web site for public sector employees. The site, marking its 50,000th subscriber, bought more than 500 free lunches for any federal, state and city employees who showed up with a government-issued ID.

As you’ll see in the video above, employees from the Environmental Protection Agency, National Endowment for the Arts, State Department, Justice Department, Internal Revenue Service and other federal agencies enjoyed free macaroni and cheese and shared their thoughts on public perceptions of the public sector.
