I have no great explanation for this... but I always look forward to calling Southwest Airlines. Not that I call them often; maybe 4 or 5 times a year. But I know that when I do, I'll be treated well. The CSR will be friendly and courteous, and will take his or her time and be genuinely helpful.
As a result, I kind of look forward to the conversation. I get happy when I'm dialing 1-800-IFLYSWA. How awesome is that!?
Okay, it's also pathetic. Fair enough. But still... kudos to Southwest for establishing the bar for all CSRs.
Now, if we could get just a li'l more legroom...
