Stuart's analogy seems better to me as it allows people to do something
else while waiting for an under-provisioned resource. And they may decide
that the wait isn't worth it at all. If the constraint moves to "entering
into the store" or "arrival rate to the grocery store doors" then the queue
just builds up in the parking lot vs the cashiers' lines. No real
difference.
