Do the garbage men leave the roll-out bin open just to be assertive?

Where I live, you pay a fee for trash pick up, and you have to have a particular trash bin that you roll out to the curb on wheels. The bin has an attached flip top lid. When the garbage men come and empty it, they always leave the lid open, which means that if it rains or snows, the bin gets a few inches of water in the bottom. Which means I have to turn it over, but even then some water stays in the bottom. And then paper or something gets stuck in it, which means the next time I dump the water out, some kind of trash comes with it. Kind of annoying.

Once, I actually asked one of the dudes if they would please close the lid when they collected my garbage, and he didn’t even answer me.

Not that I lose sleep over it, and I suppose I could drill a hole in the bottom. So that is not my question.

My question is, do they do that on purpose, as a minor gesture of personal dissatisfaction or disdain for something in their own lives?
