Mapping availability rather than assuming a window
The starting point is what each area is actually available, which is frequently different from what the lease or the building manager says. A retail tenancy that closes at six is often occupied by staff until seven. A food outlet that closes at eleven has a kitchen being cleaned by its own staff until midnight. An education space with evening classes empties at nine and refills at eight the next morning.
Establishing those real windows takes a few conversations and it changes the shift completely. It also tends to reveal that the building has more available time than anyone thought, just distributed awkwardly. A route built on real availability finishes the work; a route built on an assumed window collides with somebody in half the areas and leaves the crew improvising every night. Real availability is nearly always more generous than the assumed window, just less tidy.
