Last night I found myself at the Apple store due to a problem with my Macbook. (I own a few Apple products, but use an Android phone.) As I sat at the "Genius Bar" awaiting my turn, I overhead 3 different conversations. Bottom line: General Apple customers expect perfection and immediate service.
One man spoke little English and needed some password reset before they could help him. He was on his iPhone trying to get someone to translate, and expected the ONE tech guy to stop whatever he was doing each time he needed him, by flagging him down and shoving the phone in his face (not kidding).
Another woman missed her appointment by 10 minutes, and was upset because she was being told they would not be able to get to her before closing because she was late. This was totally unacceptable to her, and she let it show.
The 3rd woman somehow did not have an appointment, even though she swore she did. She piped up at one point that she'd been waiting 30 mins, was freezing and about to get sick, and getting a migraine. The guy asked her what the problem was and she nearly burst into tears. She needed some Windows program put on her Macbook, and was told to come to the Apple store, but Apple techs are not allowed to partition their products for customers. So now she's being told to go somewhere else (Microcenter) for the Windows guys to do the job. She was pissed.
I was laughing under my breath. I was there for an OS reinstall that I couldn't do on my own, after trying all kinds of stuff suggested from the internet. (Mine would not boot.)
So in relation to the article in the OP, Apple has created a customer base with high expectations and little tolerance for product issues.
