I'm amused by "DYKWIA" jerk behavior being tied to frequent business travelers. I see DYKWIA behavior all over the place, not just from a few elite travelers. Even infrequent travelers play the DYKWIA card. I can tell which ones they are because they loudly demand things that are completely out of line compared to how airline/hotel policies and programs actually work, and/or repeatedly emphasize their silver/general member status as if that meant anything.
There's also DYKWIA-ness outside of the travel industry. I come across people all the time with astonishing senses of entitlement and personal importance on the road, on the sidewalk, in the hallways, and even on the trail.
