Just to answer your question, Singer did tell me about the intimidation factor, and you know what? That is right on the money as to why I've always tipped the floor people. My opinion on why you tip is only based on what I've seen here only. Our friend Singer I believe is pretty spot on with his analysis on the intimidation factor, at least when it comes to the floor people. I saw where he chided you for not doing what you said you were going to do with that free play fiasco. I agree with him on that because that's what he taught me I have to improve upon. So, maybe he's right on about why you tip too?
