Washington D.C.'s Dulles International.
Let's start with the outdated, foul-smelling Damnation Alley terminal shuttles. Is this the only airport using these crazy-ass things? If so, how much did it cost to custom-order a fleet of fifteen-feet-in-the-air double-wides? And was Halliburton the lucky recipient of that contract? They probably could have had gold-plated monorails for less.
And once you ride one of these things (which drive around the same lanes as the jetliners, btw) to your terminal of choice, you are greeted by an endless line of half-closed steel gates—because everything in the airport closes at 9:00 p.m.! I had to walk the more-than quarter-mile length of the A/B terminal, without the assistance of any type of moving sidewalk, to get the last sandwich of the night from Potbelly's. And then make the long trek back eating said sandwich in front of the people who had been shut out at the Potbelly's counter moments after I ordered. Talk about awkward...
Is there any excuse for an airport that had flights going out as late as 11:00 p.m. top have NO food available after 9:00? I had just arrived on a flight that served us soda and that's it. Not even pretzels. I, and surely everyone else on board with a connection, was counting on getting food while waiting for their next flight. Awful.
