Yes, Thai memory for faces is remarkable.
Some may recall Four Seasons go go in Pattaya, a short-lived bar which I visited no more than three times and from which I never offed a guy. The ex- mamasan- whom I didn't know from Adam- hailed me at least ten years later in Chiang Mai while I was taking a walk. At first I thought it was a con, a scam.... one I sometimes encountered in Africa as a prelude to being asked for cash....but no, he really did remember me.

I seldom found the second off successful. Was it me? or the guy? I really don't know. On the other hand, when a re-match was good, it was very good!
