Definitely. Normal American customer service is to treat you like human trash, so obviously Southwest has decided to do this differently and so probably does things like only hiring friendly people, training them to be friendly and positive even in difficult situations, and checking on them somehow to make sure they're doing this and not just faking it for the interview and training. Other airlines obviously don't, but it's not just airlines, it's everywhere in American customer-facing business these days. Rudeness is just a normal part of America culture now.
