Who or what did he serve?
Drinks at the O-club.
He served drinks at the Officer's Club? TBarnett tells me he was some kind of Vietnamese war hero, so maybe he was there as some kind of spy & was hoping the drinks would loosen the tounges of any guys in the know who dropped in to have a couple of drinks. Maybe he picked up something useful to the VC government, which is what earned the awards they gave him.
