When you fly United, there are clear classes of people. First class, of course. Followed by the premiere executives. Followed by the peons. Then the serfs. Each category is treated differently (the serfs, for instance, are not allowed to use the restroom on the plane).
I like to try to do at least one thing that's above my class. My favorite thing is to step on the red carpet, even though I'm not allowed to do so. Take that, first class! Ha ha ha! My foot went where only your foot is allowed to go! Ha ha ha haaaaaaaa.
