Do you leave your trash in the movie theater?

I went to Kungfu Panda yesterday (AWESOME), and my friend and I both got a drink and little pizza, and when we left he left it all at his seat. I got upset, and picked up his stuff and mine and threw it away, and he said I was being ridiculous because people are paid to clean that stuff up.

My question is; how do you feel about this?

I work at a food service job, and am personally disgusted when I have to clean up trash that people simply leave on their tables, rather than throwing away on the way outside. It takes less than a second to pick up your trash, and if EVERYONE left all of their trash everywhere that there was “some one to clean it up,” what would those workers’ jobs be like?

Bonus if you’ve worked at a movie theater and know what this experience is like from the other side.
