Not LE
There are a couple that work that corner. The one you're referring to has dark hair and you're right, she just sits there. I don't think I've ever seen her get picked up either, but she isn't LE. Not when she's been sitting there for four years or so, night after night after night.
The other one is a blond, more attractive from a distance and probably up close. Haven't spoken to her for a while but I do remember the smoke-breath from the time I did (but friendly enough). Also not LE.
