Queue
Clinic queue desk
Who has a token, and who is in the room.
The morning opens as tokens. Each token is a person, a doctor, and a place in the line.
Arrival marks the token. The room calls the next one that is actually here.
A skip and a return are written. The line does not depend on a shouted number.
The display the waiting room sees is the same list the desk holds.
A fee can sit on the token. The receipt does not start a second queue.
Doctors have their own lines. A busy room does not steal the next patient from a quiet one.
The coordinator sees which line has stalled.
This desk books the visit and the order of the room. Clinical notes stay in the record you already trust.
A new desk clerk can issue a token and find a name on the first morning.
The close is tokens issued, seen, and still waiting when the clinic shuts.
