I've had some really awesome experiences with MSP G/As over the years - they definitely seem to have an extra sense of humor that really resonates with mine (maybe the pseudo-scandinavian heritage of the area resulted in a dry sense of humor that closely matches my own?). They're also incredibly helpful with odd requests that would simply get me shoo'ed away in Atlanta.

Delta should stack rank their gate agents in MSP and offer the top 5-10% of them a bonus to switch jobs with some JFK G/As for a while. I think the cross-pollination would do the system good - nobody ever seems happy at JFK and the "can do" attitude prevalent at MSP would be a refreshing change from the "can't do, and I'm attempting to hate you to death for even daring to ask" I always seem to get from New York G/As.
