Much as I disagree (I was one to clean up those floors), it is generally some form of "that's what I pay for you to do." People feel very entitled to be taken care of, and apparently have no shame in being seen as extremely lazy and dirty.

I get popcorn on the floor (though I've seen half a bucket poured out, likely in protest to the quality of the popcorn - we've all gotten the "seeds and casings" bag before), maybe even a spilled drink. But some people go to the movie and make it seem like at every moment they were flailing wildly. Like a showing of Phantom Thread elicited a reaction more apt for a Kevin Hart movie.

A Kevin Hart movie, BTW, being the absolute worst cleanup the theater I worked at had ever seen. I dont remember the exact movie, but it was a special screening, and he had come to do a little intro, and bought the sold out theater all a popcorn and drink. It took a very long time to clean that theater.
