My husband's 6s bit the dust recently and due to the new normal of working from home, he had to have an immediate replacement since it was his only way to receive work calls (otherwise, we'd never have gone to the brick and mortar store!). We ordered online for in-store pick up at the Oklahoma City location which is inside a mall. They had implemented numerous precautions and the place was still a madhouse. Security guards everywhere, temperature screenings, masks required, limited people allowed in the store at a time, everyone required to use hand sanitizer on your way in, employees were wiping down devices after every use. For us, since we were picking up an order, we weren't even allowed inside the store. We had to stand in a taped off socially distanced "box" and wait our turn. They weren't doing in-store set up for new devices either, just advising you to call Customer Support if you had trouble.
So...my point is, our Apple store was making every effort to keep things as safe as possible and I still spent the entire time wishing we hadn't gone and feeling horrible for all of the staff having to deal with that. I do think that curbside service would be a much better option for many locations, but I can't imagine how the OKC store would manage that just due to their set up.
