Probing a little further, I asked how long they'd been playing for. Only recently apparently and, in their words
"we first started THE DAY BEFORE YOU CAME".
I was in the same place a while back. A couple in the corner were messing around with what looked like
chess pieces, but weren't. They were also raising one hand alternately at intervals. Fascinated, I strode up to
them and asked: "WHAT'S THE NAME OF THE GAME?"
