A report in News Corp's Australian news website entitled "Sydney dad claims Apple store staff member ‘questioned my intelligence’, refused to let him pay" is an interesting read.
The report states the man, who is using the pseudonym "Calvin Scott", wanted to pay for an $80 iPad case in cash, but that the Apple sales representative kept trying to push the man to pay with Apple Pay.
The man reportedly wanted to pay with cash, or even a credit card, but reportedly was given a type of lecture about the benefits of paying with Apple Pay.
Given Apple's reputation for customer service, it would seem odd that a staff member would reportedly try forcing an end-user to pay with Apple Pay.
I've personally purchased products from Apple Stores with cash, credit card and Apple Pay, and have never had an issue with the ways I've wanted to pay.
Obviously, if similar things happen to other customers, affected people might be further inclined to tell a media company about it, but if a customer isn't receptive to a tutorial on Apple Pay at the point of Apple Store in-store sale, then maybe pressing the issue isn't the best idea.
Apple could also find ways to further promote Apple Pay, be it through in-store, online and other promotions, in its "Today at Apple" sessions (which it is presumably already doing and presumably has for some time) and maybe with more YouTube and other videos or tutorials.
Whether the episode is true or not is unknown, but it was reported as seen in the link above, so make of it what you will. Apple Pay is certainly handy, I've used it on iPhone, Apple Watch, in apps and via the Web with Apple Pay online, and I know people who have used Android equivalents.
The system works very nicely, you can even use your eftpos account with Apple Pay these days as was reported in late January 2019, but cash isn't dead yet and credit cards without any form of device beyond the card to insert or tap should never be refused by any business – let customers pay how they want, without any further sales pitches, if any such point-of-sale sales pitches occurred.
The report comes on the same day that news reports say that Apple's famous fashion-oriented retail hire, ex-Burberry chief executive Angela Ahrendts, has decided to leave Apple after five years (in April 2019), with Deirdre O'Brien named SVP of Retail + People, according to 9to5Mac.
