I have worked a job where emptying trash cans was one of my responsibilities, and it is nothing like emptying the trash at home. They're enormous, heavy, usually leaking putrid liquid, and you have to lift them above your head to dump them in a dumpster. Some of the putrid liquid will get in your hair every day, and you won't be able to get rid of the smell until you get to go home and shower in the evening. It's hard to appreciate how bad of a job it is if you haven't done it.
