I am sure there will be places where this is still the case.
The main lounge at SKG (used by practically every airline apart from A3) used to be like this last year. It's probably closed now, as OA have opened their own lounge and, between themselves and Aegean, they can easily cover the tiny number of premium pax passing through the a/p (I've been on flights where WHY was so full and C so empty that they simply did away with the curtain and had an all-Y service).
