Amazon will counter by convincing third parties to resell their goods on the shelf. Amazon takes their cut of sales, but doesn't chip in on losses or fraud. Oh wait...
It's a nod to their online model. You sell android phones as a 3rd party on Amazon.com. Buyer claims "not as described". Keeps phone, puts potato in Android box and returns it. Amazon forces you to refund. Probably distressing to Amazon that they can't foist off losses of physical in-store shoplifting onto 3rd parties.
They realize that amazon now measures the height of each customer, also has a miniature drone following them around and each floor tile measure the weight of the people for that extra data point, oh and some have employees disguised as customers whom help the system when in doubt.
'Who help'. 'Whom' is the objective case, parallel to 'them'; a good way to test the correctness of a particular use is to substitute the latter for the former and see if the sentence is still grammatical.
Interesting. Your post got me to finally look up the history of this [1]. Apparently it was a woman with an umbrella in a 1975 study, but made extreme by Simons in 1992 with the gorilla. The moonwalking bear is apparently from a 2008 Transport for London advertisement [2] to remind people to see cyclists.
And "a lot" here is 20 customers. For any decent shop they'd probably need to track at least 50, rather 100 during busy hours. Not sure if they can fix that within a few weeks.
