Every lobby on one screen.

Front desks are staffed for peak, then paid for all day. Each location has to be able to handle its busiest ten minutes, so it carries a person through every quiet hour as well. Multiply that by four locations and you have four people covering four peaks that rarely happen at the same time.

A pooled team sizes to total demand instead. The portal is what makes pooling possible: one view, one queue, and routing that sends the next visitor to whoever is available anywhere in the estate.

The lunch hour. A single-desk site has an unavoidable, predictable daily gap. A pool does not, because the coverage was never tied to that chair.

The call-out. One person out sick is a scheduling adjustment rather than an empty lobby.

The next location. Opening a site adds a screen, not a hire, until total demand justifies another person.
