Pentagon slugs at Bob's

For those of you who use Bob's in the AM, you know that the slugline is split in two. One line stands on the church side of the lot, and the other line stands at the Long John Silver side of the lot. Over the past two weeks, several cars have pulled up to one line calling out for Pentagon riders only to be redirected to the line I'm in (the one for 18th and 23rd streets). When the car reaches our line, we tell them that the other line is for the Pentagon.

So which is it? Or does Bob's not serve the Pentagon? No point in giving drivers the runaround...
