Back when I worked as a dishwasher, I also had to clean up certain areas inside the "restaurant". It was a shitty "restaurant" placed in a theme park.
Anyway, one day some fat cow brings her little child into the restaurant, the little child probably realizes what kind of shit food his mom is feeding him, and he pukes all over the floor.
My manager said I had to clean it up. So I had to clean up this disgusting puke, while the fat cow just sat there staring at me, chuckling a bit "hiihii, what a mess, these things happen huh". Yes they do, and when they do you fucking clean up after your own spawn, whom you are also feeding poison.
I resigned shortly thereafter, getting some holiday money were not worth that shit. At least it gave me some perspective into the lifes of people with shitty jobs.
