Scientists discover what I been sayin’ about grocery checkout lines

Consumerist - Math Proves It: Grocery Store Express Lane Not So Express:
The conclusions, after studying the lines in his local store as well as cash register data: it’s people that slow down the checkout process, not items, and the express line is slower when all other things are equal.
Yep. If there are two lines to choose from I look at the amount of groceries and the number of people. I always pick the line with the fewest people if the total amount of groceries are anywhere near equal. It’s the loading and payment times that kill speed.
