Zig Zagged: The Stacy's constantly changes their waitresses' outfits: sometimes they are very revealing, sometimes they are not.
Averted: The waitresses dress reasonably.
Enforced: The male writers decide to make the waitresses at Stacy's Diner wear skimpy clothing for the Fanservice.
Lampshaded: "Boy, look at that waitress. Is this place a restaurant or a strip club?"
Invoked: After a change in management, the new manager makes the waitresses wear sexier outfits.
Exploited: The waitresses wear revealing clothing to increase the diner's male customers.
Defied: The manager does not want to sexualize the waitresses by making them wear sexy clothing, so they all dress conservatively.
Deconstructed: After a few weeks, the customers at Stacy's consist almost exclusively of lonely male perverts who care much more about ogling the waitresses than about the food. Behind their smiles, the waitresses work in constant fear of sexual harassment, which in fact does happen on occasion due to the heavy temptations, and many of them sue the restaurant and/or quit.
Reconstructed: For this very reason, the Stacy's have a strict customer policy against sexually harassing the waitresses.
Played for Laughs: The waitresses dress sexier than normal, but the diner's idea of "sexy" is Lady Gaga. They wear a garbage can lid for a hat, a dress made of Steak-Umms and a pair of wellies covered in glitter glue at work. Hilarity Ensues.
Played for Drama: A group of waitresses fear that they might not be able to fit into Stacy's Diner's new waitress outfits, which are a lot more hotter, a lot more sexier, and a lot more revealing than the previous one. For this reason, some of them quit.
