> To be fair in this case, self-service is objectively worse than having the shopkeeper grab everything you want.

even this depends on the type of shopper you are. if I'm buying a bunch of pasta, curbside pickup is great, and delivery is even better. but if I'm buying an ny strip, I want to see all the choices and pick the one that looks best. similar for fruits and vegetables, I don't trust the professional shopper to evaluate ripeness on my behalf. some things you just have to do yourself.
