I do appreciate when a worker in a restaurant has a legitimate conversation and is social, if they can see when it's appropriate and welcomed. And to add context, I'm not talking about the waiter hovering like you're describing, I'm talking about something I've only ever seen from immigrant family restaurants where they've come from a culture where eating is still a social community activity, or possibly when a chef takes pleasure in knowing you're enjoying their experience. The always transactional nature of eating in society has started to annoy me. But it's very different to when someone is being paid to try and make your experience good, that's inevitably plastic and coerced.
