Tokens
Token queue
A counter, a token, and the person who is next.
A token is issued for a counter. The display shows the number now being served.
The counter calls the next token. A no-show can be skipped and still recalled.
Each service can have its own line, so a short job does not wait behind a long one unless you want that.
The waiting room display and the counter read the same list.
A token can carry a name when the visit is not anonymous. The public display can stay a number.
The supervisor sees which counter is stalled and how long the next person has waited.
At close, unused tokens are still listed. They are not silently dropped.
A new operator can call the next token on the first hour.
The desk fits a bank counter, a clinic, or a service window. The words on screen are the words you use at the glass.
The day's record is tokens issued, served, and skipped.
