When gadgets betray us?

A New Zealand chain of no-frills supermarkets had its computer turn on the lights and unlock the doors of one of its stores at the normal opening time of 8:00am on Good Friday, a holiday on which there were no employees present. Apparently someone called the police at 9:20am reporting that truckloads of groceries were being removed but several shoppers simply went to the self-scan checkout lane and proceeded in a normal fashion until one shopper happened to scan alcohol and the scanner automatically stopped functioning while it awaited managerial confirmation of the purchaser's age. It appears that some shoppers who entered the store simply left when they realized something was amiss. Apparently there were those who took advantage of the situation though and prompted the calls to the police. Police in New Zealand are of course not armed but had no trouble dealing with the situation and the store's manager intends to take no action during a period of time in which he trusts the various shoppers will voluntarily do the right thing by coming in and paying for their groceries now that the store is open and properly staffed.
