Everything you just named can be automated entirely
have a fucking pill ATM where it scans your ID and gives you the pills you need
self-checkout is just the beginning, there's already "virtual" stores where you pick your shit in VR and it gets delivered to you, and the delivery can be handled completely by robots
automated farming is already a thing
customer service is already being replaced by AI chatbots

It's costly as fuck for sure, especially on large scale, but absolutely possible
and who's to say, people will probably invent some soilent green shit that can imitate any and all foods with maximum nutritional value, and we'll replace any traditional food with it
