Some asshole at my work spilled nearly a whole pot of coffee in the break room and left it there. Got on the counters, the floor, into the drawers with the coffee grounds/utensils/etc. People were curious and the attitude was definitely “man someone is a bumbling fool” but if there weren’t janitors to clean it and we say, drew lots to decide who had to clean it up there probably would have been a witch hunt instead, which would encourage the person who did it to just clean their own mess.
Which is just a long winded way of saying that I agree, office workers need to be forced to clean up after themselves.
