I'm a lobbyist and frequently arrange briefings in the Capitol building. Here's a weird fact about the catering company that has the contract for the Hill: if you ask for pitchers of tap water instead of bottled water (which I tried recently), the company charges you $100 for a "wait person" to - what? - pour the water. It's a complete boondoggle, and I suspect this may be part of the explanation for the figure above. And to be clear: this isn't the lawmakers...it's the crappy catering company.
