I realize this is awful 4chan of me; but that seems rather beta of you, in that you're essentially swayed by the flow of traffic of the establishment, in a scenario where you're supposed to be getting shit done. You make it sound like you're only privileged to be there when it's convenient for the coffee shop owners, and that seems to me like a tense place to exist.

On the other hand I can relate to the concept of doing good by those whom you rely on, a symbiotic relationship and what not. That's a very pro-society thing and I suppose that's respectable.
