Two workers are quadratically better than one (2020)
See also "Why the other line is likely to move faster" [3:42] by Bill Hammock the Engineer Guy https://youtu.be/F5Ri_HhziI0The very short video touches on Agner Erlang's studies on telephone block queues and how shopper wait times are reduced by having cashiers share a common queue.

An excellent video on the phenomenon from the "Engineer Guy" series: http://www.youtube.com/watch?v=F5Ri_HhziI0And just in case you feel like killing about 20 minutes of your day, check out the rest of his videos. They are excellent.
⬐ missing_cipherI love his videos. I wish he would make more. The harddrive one was interesting.

⬐ arctangentThe video doesn't explicitly mention this, but if you want to minimise your (perceived) relative waiting time you should choose one of the two end aisles to queue in.⬐ hrabagoIt's because I'm cursed, and I always get the slowest line during checkout. It's okay, though. I make up for it by always switching to the faster lane while I'm driving.Kidding aside, I like his way of presenting. I have an appreciation for good presentation skills, especially coming from techies/engineer types.
