Interesting that there's still smalltalk in such a job. I always imagined that fitting into a specific image of an ideal person/worker is a burden that you have to carry in white-collar corporate jobs, while in low-end menial jobs you can just be your own grumpy self if you want to be, as nobody gives a damn as long as you get the job done. It was even portrayed in one episode of Black Mirror, where a truck driver was the only person free to express herself (because there was nothing she could lose, her job was not desirable).
