I don't recall if there was any food involved but ....
My most expensive bar was for a function I paid for as a result of getting saved from some damn hairy life-threatening situation in Viet Nam.
We were on patrol on some uncharted river and got surrounded by a huge force of the bad guys and it was bad enough that it was almost impossible for a bird to land and pull us out.
It just so happened that a copter from the 101st was listening in, heard our situation, and made the decision to come in and get us.
Long story ...... but we got back to base-camp in one piece and my CO met us and invited the 101st Airborne to a get-fucked-up party the following week. It was sort of traditional for Marines to throw a party for anyone who saved our ass and since my ass was pulled out by the USA 101st and because I was the senior dude, I was obligated to pay for any expense involved......
And DAMN!!!... it was one hell of a party. Even the Aussies who were fighting their own battles many miles north of us showed up and helped us make that party one of the best ever held under combat conditions. (My opinion.)
Actually it got a bit insane and the MP's had to break us up so some of us hopped into one of the waiting 101st birds and ended up in a small but unexpected mid night skirmish just a a few clicks away.
I think we paid thrity-five cents a drink and a twenty-five cents a beer at any US club in Nam and my bill came to a bit over $1,500 and I quickly learned to never go into combat unless you are completely sober because strange things happen when you're drunk in a pitch black jungle war zone.
BTW - after that short skirmish - We continued the party but this time at the Army base and I have no idea who paid for that one.
I was actually AWOL for 36 hours but when I returned everyone was still a bit fucked up and no one noticed my absence - plus my CO liked to see his troops have a good time whenever possible.
One of my few fun times in VN.
