My parents go to a kitbar (wine bar with open kitchen and waiters/bartenders who cook) every Wednesday night and have for a decade. They know the staff and have friendly chats with most of the people who work that shift, and it's a nice break in the week for them to get to chat with some young people who aren't their descendants. I come along when I'm in town, and everybody seems happy and cheerful. People work that kind of job, as opposed to, say, data center technician (a big career in that area) because they don't mind making connections with strangers.
