After grappling with the problem of cleaning communal spaces with multiple sets of roommates and in company breakrooms and kitchens I've come to a couple of conclusions: 1. Even in an environment with conscientious and considerate people with the best intentions, there will be a non-zero amount of "whoops I totally forgot to throw that out". People aren't perfect and they forget to do things sometimes. 2. At scale (for instance a company kitchen shared by an office of 50 people) even a 1.5% error rate will result in at least 2 "this should have been taken care of but wasn't" incidents per day (assuming each person goes to the break room 3 times/day). 3. The real error rate is likely to be higher than 1.5%. I consider myself a considerate person (eg. at work I load cups I didn't use into the dishwasher so the sink isn't full, I wipe off the countertops when I see them dirty etc.). But I'm sure even my own personal error rate is higher than 1.5% (eg. I'll bring a coffee cup and a water glass and forget one of them on a kitchen table when I go back to my desk; now that forgotten glass is someone else's responsibility to clean up). What this means is that unless most of the people who use the space take ownership of problems, regardless of who created them, you're always going to have cleanup issues. I don't know if it's possible to create that type of culture.
