What’s worse than the Nationals losing on opening day? Watching the game end without a buzz.

The Post already wrote about the long lines and frustrated fans at Opening Day. Turns out it was worse than they thought. According to a law-enforcement source who watched the game, the concessions in the 400 section ran out of beers ($6.50) in the middle of the fourth inning. C’mon, you guys! According to Nats320, Aramark, the megalith concessionaire, also ran out of dogs.
