I've had Delta FA's personally welcome me, a mere Delta Gold Medallion member riding in cheapo class, several times after takeoff, and once an FA even gave me and a travelling companion free headsets, just because I was a GM. The FA's noted each time that Delta appreciated my GM business, and, if this happens more often in the future, it may even lessen some of my bitterness over Delta's 2001 Skymiles "benefits," which we all asked for! The ground and air staff can be outstanding, when they go out of their way!
