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.

The failure rate per transaction across multiple stores and multiple types of stores indicates that even with small "express" sized baskets, the failure rate per transaction is 10% to maybe 5% and it takes so long to get stuff fixed that its faster to use a human cashier, on average.
Of course that leads to self selection so at home depot the human cashier has to hand count 72 paver bricks because she doesn't believe in the astrological numerology of arithmetic multiplication and of course the victim has no idea the UPC code or cost per brick or qty discount and it just all turns into a giant disaster. Times like that, I'll risk the self check, I mean it can't come out any worse.
