Throwing of the trash bins was literally the first thing I was told will get me fired quickest when I started as a trash driver. It was drilled into me that if we can't place it down where we picked it up, then the most we should do with it is turn it upside down and slide it back. They recognized the hurry in which we needed to work, which is why we were allowed to slide it over, but it was definitely a sin to throw a trash can.
