What is up with the insanely hard to figure out Shopin Teleport?

The Shopin teleport teleports you on top of a building, and from what I see when the textures glitch out a bit, you're supposed to be on the first floor of the building... How in the hell do you get down there, and would somebody please not make things retardedly hard to find out for yourself like that. >.>
Also, same thing when you first spawn... There's all this stuff on the ground it looks like we were meant to use, yet no possible way to get to it. You're completely boxed in inside a ceiling ontop of a house. >.<
