Good Customer service is very contextual. A bank teller line or a counter where you order fast food should be fast, efficient, while attempting to be rude and uncaring. But, you'd want your doctor to be at least personable and a waitress at a full sit down restaurant needs to be able to converse with diners. Service also needs to be cognizant of overall "load" on the environment. It might be ok to chat when there's no one else around, but not when ten people are waiting. It's a bit of a balancing act and so few people providing service really understand it.
