Would the layout of the lab work better if instead of going into the tower, down and /back/ behind you out, to turn the lab portion of it around so you can go into the tower, go down the elevator and without turning around, right out to meet the clients.
I think it makes for a quicker transition in between soliciting clients and right to playing with them... something I picked up from level design in other video games.
And personal perception... I always thought having to turn around to meet the clients was a little off, it toyed with my habit of going from the secretary right to the client. I've even looked at jumping the rails to get to the lab a bit quicker if one of the clients looked really hot.
