Back to Xander and Spike. Xander: "The point is I work hard for that money you stole it." "And you're making it into very hard work," snarks Spike. Ah, someone with a work ethic I can recognize, if not respect. So the whole point of this is that Spike notices that Buffy and Ben are talking and gets all worried.
A train pulls into the Sunnydale station, where the last working porter in America awaits. As the train comes to a stop, the porter seems surprised that nobody is disembarking. I wouldn't be. It's Sunnydale, for God's sack. Now if it were the train departing Sunnydale, that would make a lot more sense. So the porter goes inside to investigate. Uh oh. It looks like someone couldn't wait until they got to the dining car. Of course, to a vamp (oh, did I spoil that for you? It's been so long since we've had a real vamp on this show), I guess the whole damn train is a dining car. The porter catches sight of something, turns around, and runs screaming for the exit. He almost makes it, too. And thus endeth the last working porter in America.
