I am way too lazy and care far too less what others think (in this case judgy pilots on the interwebz) to disrobe out of the uniform for a stop by the grocery store on the way home. I have one thing in mind at that point, and it is getting home to my wife and kids.
I never minded the "are you a pilot" inquiries. That's an easy smile, "yes," and carry on.
When I taught in the sims, the lanyard said "Delta Pilot Training." The amount of times I got "oh good luck, I hope that works out for you!" was pretty funny. Once or twice I was like "oh, I actually give the training," but for the most part it was just a "thanks, me too."
