That seems like a miss. I don't understand why, if they have such good technology, they wouldn't just have sensors on the trashcans or toilets that inform them when they need emptying/cleaning.
If you were building a system like this for real, you'd probably put sensors on toilets and trash cans in addition to the cash register connection. Real sensors fail, and, in a system where workers are explicitly discouraged from using common sense, that leads to overflowing trash cans.
