"Because all of you of Earth are idiots!" shouted Tom, wearily wiping the glass counter, removing coconut oil from the reflections of overpriced candy bars. Inside the theater the movie echoed him: "Because all of you of Earth are idiots!"
Tom sighed, not for the first time that evening. The Manager, who paid in cash every Sunday, had decided to take advantage of the bizarre tastes of his Generation X clients and offer an Ed Wood film festival. Bride of the Monster, Plan 9 From Outer Space, and Night of the Ghouls ran on the second, smaller screen on Friday, Saturday, and Sunday, two bucks a head. The Manager was making a killing.
Tom, who needed the job in order to move out of his parents' trailer home, found little about the Ed Wood canon amusing, although it was light-years beyond anything by Coleman Francis. Even so, Tom had been forced to hear the dialog of each film, on Friday, Saturday, and Sunday... He only had to watch them once, having filled in for the Manager's weasel-featured nephew/projectionist Neoldner, who had called in sick to buy grass in Beloit. But he would have been able to forget the experience had it not been for the penetrating soundtrack which bled into the lobby.
The ordeal, for tonight, was almost over - the concession stand closed after Plan 9. He hoped he had sold enough to keep his job - there was the worry that the Manager would increase his profit margin by manning the concession stand himself. But the Manager strolled out of the second theater with a broad grin, revealing his cutting overbite.
"I don't know why," the Manager exclaimed, "but they love it!"
"Most of them are from the 'Ed 9 Film Society,'" Tom replied. "By the way, I need to restock the chocolates."
