There were 12 of us civilians on a golf trip a couple of years ago. We were having breakfast at a restaurant not too far from a small military base. There were 4 guys in uniform also eating. As they were finishing up I slipped over to the counter and paid their bill. Minutes later they came over to our table to say thanks. My fellow golfers wanted to participate in the good feeling but I refused their cash at that moment. Later, one or two at a time they approached me offering to split the bill with me. They wanted to participate in the gesture so I accepted, and I ate free the rest of that trip.
