A Walmart employee was tragically trampled to death on Black Friday by anxious shoppers standing in line to enter the store. The employee, a 34-year-old man, suffered "an undetermined death" when a "throng of shoppers ... physically broke down the doors, knocking him to the ground." Might have been different if the lines had been absent and QLess had summoned customers to enter one at a time using the QLess touchscreen-activated digital turnstiles. With QLess, nobody can cut the line, and so the rush is replaced by an orderly flow.--Alex
