I just remembered that Steve Landsburg wrote about this a while ago for Slate, in the context of joggers waiting for water fountains.

Yes, if you could jog indefinitely, and if you could prevent &quot;meta queueing&quot;, then you could make it so that there would never be a line at the fountain, but that&#x27;s not a good model of joggers&#x27; needs.<p>[1] <a href="http:&#x2F;&#x2F;www.slate.com&#x2F;articles&#x2F;arts&#x2F;everyday_economics&#x2F;2001&#x2F;02&#x2F;the_first_one_now_will_later_be_last.html" rel="nofollow">http:&#x2F;&#x2F;www.slate.com&#x2F;articles&#x2F;arts&#x2F;everyday_economics&#x2F;2001&#x2F;0...</a>
