Sort of, but CoS/QoS could be described that way too? But at least it's based on the quantity of items, CoS/QoS would be more like "moms with kids go in this line, business execs go in this line, everybody else in this other line" and "we have 4 checkers available for the business exec line, 2 for the mom&kid line, and the remaining for everyone else". Maybe the best is: I'm standing in long line with a huge cart of groceries and there is a person behind me with only 3 things, so I tell them to go ahead of me so their wait time isn't even worse. But usually this happens because the people in line make it happen, the checkers default to FIFO out of "fairness" (for some value of fair). Maybe car-pool lanes are a good analogy, but some of them are HOV and some of them allow you to pay to use... Also couldn't resist :) https://www.youtube.com/watch?v=RGWiTvYZR_w -- Matt Taggart matt@lackof.org
