Just out of interest, how is "items per minute" measured? Does it include the payment process or does the clock stop between the last items of customer A and the first item of customer B?
Here in Italy I'm regularly confused by the pace of the cashiers. Sure, they talk and smile a lot, but even at their best they take over a second to draw an item over their desk in a manner that it detects the item. Back in germany I usually went to a shop where they managed to deal with 2 to 3 items a second. They have really well trained personell that works like machines. Combined with electronic payment with less than 10 seconds from the last item to getting the receipt taking part in the process is really stunning from an Operations Research point of view - if you had time to think about it while hurrying to keep up with the pace of the cashier.
