I don't agree with this argument.
When I want to socialise with people, I'll go to a bar, my friend's house, a coffee shop, etc. If I want a burger, I want to get issued with that burger ASAP, without having to deal with someone who you may consider to be a nice person, but I may consider to be a douche-bag.
If that well-paid smiling person didn't have to work at the burger place, she might have something more interesting to talk about when we meet in a proper social environment.
