I think a lot of it might have to do with the non-linear way cleanup needs to scale with the number of people. If you have 10x people living in a space, they are probably creating around 10x as much of a mess. And because there are 10x people there are 10x people experiencing the messes. So with the broken glass example, you probably have 10x broken glasses per time period and 10x people wandering about risking to find a small glass shard you missed. So cleaning up a broken glass in a 40-persons household needs to be way more thorough than in a 4 persons household.
(It’s also why using glassware near your personal pool is fine while using glassware near a public pool tends to be prohibited.)
How about, “incapable of cleaning up after dropping a glass”?
(Not trying to be mean; I was very surprised to read that this was the kind of thing they relied on Cathleen for)
