Scientific Proof That the Other Line Probably Is Moving Faster

As your frustrations with waiting in line mount this holiday season, it may be some comfort to know the scientific trappings of why, exactly, you're stuck for 20 minutes behind the lady who insists on a dozen price checks.


I'm mostly surprised that there's a reason Trader Joe's and Whole Foods opt for a single queue. I always thought that was just, you know, trendy. [Engineer Guy via The Daily What]



I'm guessing one problem with the single line idea is it takes too much floor space, which is at a premium.

Our local Borders uses the one line concept and it actually takes up very little space, but then the customers don't have shopping carts.

Using one line at Wal*Mart probably wouldn't work very well since it'd be so long, shoppers are transporting more goods in carts and typically are not singles (they have other shoppers with them).
