Sequence matters more than duration
If the store is cleaned last, everything carried out of it crosses a floor that has already been finished, and the front of house has to be touched again. If it is cleaned first, the route is cleaned afterwards as part of the normal sequence and nothing is done twice. That single decision often saves more time than any change in method, and it costs nothing to write into the scope.
Sequencing also determines where equipment sits during the attendance. Staging gear in a doorway or against a service counter is how it gets in the way and how it gets damaged. Agreeing a staging point, and an order that moves from the back of the premises to the front, gives the crew a route that works and gives the venue a predictable pattern it can plan around.
