How long is this line?!?

At a recent convention that I attended, they attempted to organize and maintain a few separate entrance and exit lines. With hoards of people constantly coming in and coming out, definitive pathways were utilized in hopes of maintaining some semblance of structure. They had a couple of volunteer staff stationed at different places to ensure people didn't attempt to circumvent the system in place. Yellow caution tape was barely hanging on to the makeshift barricade. They allowed people to leave through the two sides or down the escalator. People were only allowed to enter going up the long flight of stairs or the escalator going up. Neither choice was a good one. Most of these people entering this area were extremely exhausted as it was. Having them walk up a long flight of stairs slowed the process to a near standstill. For the lazy and extremely tired people, they believed that taking the escalator was a great idea because they could stand there and have it slowly carry them up without having to waste any energy or effort. That line was a complete standstill.

Both of these temporary lines were there to help maintain a good flow of people constantly going in and out of the room. The caution tape dissuaded no one but a volunteer staff member was there to ensure people didn't try to go where they didn't belong. Many would walk into the building empty-handed, but that would change after exploring the exhibition hall. People hurriedly rushed into the exhibit hall and went off in different directions as stands were separated into at least twelve aisles. All the aisles led to the exact same exit and it was a definitive pain in the rear to leave. For those who came in empty-handed, nearly all of them left with at least two or three bags of goods either as gifts or souvenirs.
