I think I told this story years ago. Woman sits down next to me playing 100 hand QQs. Gets dealt 4,4,4,3,1.Goes to throw the 3,1 away when I said that you already have QQs. She proceeded to tell me to shut the f---k up and not to bother her she was trying for 4oak.
Why would you try to teach others how to play at the casino? You deserved to be told to shut the f---k up.
