What if it was 30-50 minutes longer? 3-5 hours longer?
Yes, there are human beings on the other side of our daily transactions that should always be treated with respect. However, these are transactions, not social calls.
I live 10 minutes away from an Ace hardware, 20 minutes away from Home Depot. I almost always go to Ace and pay a few dollars more because when I walk in the door, somebody immediately asks me if they can help me find what I'm looking for. They walk me to the isle and spend a few minutes discussing the various options. If I had to communicate awkwardly through a tablet, I'd honestly just spend a few more minutes driving and save the money.
Sales is a communication-heavy job. It's pretty common already to offer extra pay for bilingual associates. I don't see what the difference is here; nobody would hire me for a job selling in Mandarin, even though I could run Google Translate on a tablet.
Fixed it, and maybe. A decline in customer experience provides incentive for Apple to optimize the slower customer service folks out of the picture.
