The service quality must vary quite a bit by store. Here in Portland, Oregon, I’ve been to a couple of different Apple stores and I’ve always had great service. For example: I walk in, I’m greeted, I ask where something is, they point it out, I pick out what I want, buy it from a nearby employee using Apple Pay on my phone and walk out. Even in the huge store downtown - there are tons of people, but enough employees that I never have any issues. In the Tigard store, I walked in with an external DVD/CD drive I bought used on eBay that had stopped working weeks later. They looked me up, saw I had bought MacBook Pros in the past, handed me a brand new drive. Other areas must have awful Apple stores, looking at all the negative comments. My wife and I are always impressed with the service in Apple stores around here, it’s kind of over the top, weirdly good.
