Ten to nine on a Saturday.
The owner logs in and checks who is on today; two barbers are flagged open to walk-ins all day, one is bookings-only until noon.
The queue screen in the window already shows a twenty-minute wait because three names joined online from home.
A regular walks in, taps his name on the tablet by the door, and the system recognises him: same skin fade, usually with Dean.
He takes the next free chair instead, because Dean has a booked client and the quoted wait is shorter.
