Who needed a fake ID in Athens? We just walked right into the bars as freshmen (1979). I had the same pleasant experience at the State Liquor Store.
They never carded anyone in my days 1977-1981. The story I heard back then from a bar owner was that the local police know it was going on. Once every few years they would bust one of the bars. The owners knew they had to take their turn every once in a while.
For those of us of a slightly earlier vintage (1970-1976), we all carried fake IDs so we didn't have to drink 3.2 beer.
As a historical note, while some states had a different age for 3.2 beer, in 1972, thirty states reduced the drinking age to 18 for all beverages By 1982 thirty six states were at 18, but because increased traffic deaths, by 1988 the drinking ago was back to 21 in all 50 states.
