It's rather impossible to screw up an ATM(unless one intends to). Send 6 people to the U-Scan and you have absolute chaos. Send 6 people with a few items into a checkout line and they'll all be out in minutes.
What usually happens at the U-scan is all the alarms, bells, buzzers, and wistles end up going off at once. People end up waiting around impatiently for "cashier assistance" while the lone cashier at the helm has 4 other people to have sign their credit card slips, dispense change to since the machine jammed up, enter a birthdate for a 60 year old man to buy alcohol, and tell the kids at U3 to stop sitting on the scale.
Not evolution in that in the end, it's more trouble than its worth.
