Why one visit cannot hold a continuous site
In a standard office the building empties overnight, so a clean at the end of the day is still largely intact in the morning. On a transport or distribution site the drivers, pickers and yard staff working the next shift use the same amenities within the hour. The clean is real and the benefit is real, but it decays from the moment it is completed rather than being preserved by an empty building.
That has a practical consequence for how a site should judge the service. Inspecting at the start of an attendance tells you what a full cycle of use produces. Inspecting immediately after tells you what the attendance delivers. Both are useful, and confusing the two is the most common reason a continuous site concludes its cleaning is inadequate. Recording both inspection points in the scope makes the comparison fair.
