I forgot about this one. There was another time where I joined a game called CoA 4 HR. Knowing to expect it was someone who would somehow try to bull**** me, I simply go in, show him my Ber, and he shows me a very nice CoA. When I check the green, the screen drops and he apologizes saying he clicked the wrong button. When we go back to the trade screen, exactly as I thought he would, he places a fake Crown and quickly checks the green. This time I surprise him and exit, then apologize saying I clicked the wrong button. The guy, thinking I did not notice his fake, quickly repeats the process however this time he places the real CoA by mistake. We quickly trade and we both stand there in silence for a moment. Then the guy says something like, "oh... uh, could we trade back?" and I simply leave. One of the rare times a scam backfires.
