Was backcounting some shoe games the other night, and kept running across this chinese guy who was sitting at the 25 dollar table. Well, i finally was back counting the table he was sitting at, and when the count got good, i jumped in. Had a 16 vs a dealer 10, and i stood the hand. Then he turns to me and whispers "Professional Huh". And i just look at him, and was kinda surprised that he said it, i didn't say anything to him though, didn't know what to do really. Should i be worried that other players can tell i'm counting? I really don't try to hide the fact that i'm counting, but i was still a little concerned. What do you do when someone approaches you about counting?
