There is no sign that the people there know Leon, or were expecting him. There is a sign that someone did, however, because a relay roto-drone takes off quickly. It's uncertain if it's also going to track Leon, but it could also be meaningless if it does or doesn't as another drone comes in over the car and starts to rise up.<br/><br/>Unaided eyes would have a hell of a time seeing it without following the drone and considering that Leon is being distracted by the sheer awkwardness in the shop, he's probably triply unaware that he's being spied on.
