The Canadian Broadcasting Corporation reports on a former math teacher who claims to solved the question "Which checkout line up will be fastest?"
In a nutshell he has concluded that the number of people in the lineup is more important than the number of items a person has in their cart.
The critical factor, he says, is the average of 41 seconds that it takes a shopper to pay the cashier and engage in idle chit chat.
So a long line of people in the Express line, with two or three items each, will actual move slower than the checkout with one guy with a full shopping cart.
YMMV.

Growing up, most supermarkets had automatic scales (with an attendant nearby) to print a barcode for your produce in the produce aisle. Seal the bag, print, stick it on.
I'm not sure how many people tried to cheat, and how often the cashier would catch them, but the concept lasted long enough to believe the loss was worth the time savings.
