Spit, probably. If I recall, the hotel was in the old Plaka district at the foot of the Acropolis. Athens in those days, a few years after Greece had emerged from military rule, was delightfully seedy ( Barcelona, a few short years after Franco had kicked the bucket and long before the port was cleaned up for the Olympics, was also great fun then - grungy and working class but not as run-down as Athens, and with some good contemporary residential design, built for ordinary people ). There weren't many gay bars in either city then, and one met local guys by cruising parks and getting invited back to their apartments. Or, in the case of this Athenian, to a hotel of sorts. I recall him telling me it cost quite a lot of his weekly wage to go there.
Sometimes I wonder what happened to all those easy-going, Mediterranean gay men from Shockers European Vacation of '78/'79. Mostly dead, I expect.
