Same thing happened to me when I was a young air force guy.
Out to dinner with my girlfriend in Monterrey, an older couple paid for our dinner. He told me that when he was back from WWII someone did it for him and told him he had to do it too. He waited about 39 years and I happened to be the lucky airman.
I did not wait 39 years but have made it a habit of buying dinner, drinks or what ever for our young people in uniform.
Makes you feel great and makes them feel really appreciated..
It's people like you that give Freepers a good name. Thanks for supporting the troops. For once we get to see a great human interest story about our wonderful kids serving the armed forces.
It feels great. We've done it for elderly couples, too.
