let's say, hypothetically, that i went to the movie theater, and the movie i was watching happened to be three hours long. for the sake of the argument, i am about halfway through watching the movie, and i have to go to the bathroom. based on what's happening on screen, i can determine that an important scene is coming up, and that i need to see it if i want to understand the plot. what's stopping me from pissing in the drink cup they gave me for my dr. pepper? if i can do it quietly enough, no one is going to be able to notice what i'm doing, and, in my honest opinion, pissing in the drink cup is a much better alternative to using the bathroom, since i would've missed an important plot point had i chosen to do so. lastly, no one would have to clean it up afterwards, since it's all contained within the drink cup, which is meant to be disposed of after the movie anyways, and, as a result, will not affect the theater staff in any way whatsoever.
