Why else would someone who works at a place so isolated that would mean you could never possibly see each other again, say such a thing like “see you later”?

You are in a petrol station in the middle of no-where buddy, and there is no chance that I’m coming back this way any time soon.
But maybe, weird neck-beard dude, you know something that I don’t. And that dream in which we meet again is closer than I could possibly imagine. In dreams weird neck-beard dude, in dreams.
