I always feel pretty weird about offering to buy a military guy a drink or something.
Do you get a good response?
Many times, while trvelling, I've seen young Marines be unable to buy a beer at an airport.. because of age restrictions. Believe me, there is nothign sadder than seeing 4 or so young Marines, fresh out of boot camp, ( they have that incredibly scrubbed looked..newly minted..) I'll always buy a few, then walk over, put them on the table, sit down and talk with them..( and they always want to repay you...)and start reliving my youth..
Never had a negative response.
Merry Christmas
