Assume the application implements an unbounded min-priority queue.
A customer joins the queue behind all customers already queueing with the same priority. All customers with priority value 1 are queued in the order they joined, before all customers with priority value 2, and so on.

For example, if customers join the queue in this order:
Customer | Priority value |
---|---|

Tang18 | 1 |
Eber87 | 1 |
Green201 | 2 |
they will be queued in this order, where the left end is the front of the queue:
