Holy crap, the things people worry about. I just learned that there is a group of people that think it's disrespectful to ask "so what do you do" (for work), in conversation when meeting someone new. I just see it as a nice conversation starter that usually leads to family, hobbies, etc... All it showed me is that people get worked up over the dumbest stuff. If a Captain offers to buy, take them up on it, they're not doing it to extract anything. If the FO offers a coffee, take them up on it as well. It all works itself out in the end and it's just beyond ridiculous to worry about these things. I guess you can add this to the list of reasons I much prefer to just do turns and never overnight lol.
Post written after a good friend/squadron mate/Deltoid/APC dweller showed up to my house unannounced with a six pack that has now been downed. He's even an FO, so I guess I shouldn't have let him buy the beers we drank.
