Construction and job sites
A job site is never the same shape twice. Units get moved as the pour progresses, the gate code changes, a foreman calls for two more on Thursday, and the site that was mud in March is a paved lot by June. The office plan goes stale quietly, and the first anyone hears about it is a driver on the radio asking where the units went.
Unit pins fix that at the source: the driver moves the pin from the site, the office sees it, and next week's route is built from where the units actually are. Service windows and gate notes ride along on the stop, so a locked site is a known constraint rather than a wasted drive.
