"cash in the rest and then quickly vanish behind the nearest bank of slot machines."

What about the eye in the sky. I always harvest just before IM ready to leave. Sometimes I go in and out. I can have a stack in my pocket in less than 5 mins. Other times I go about shift change. Hit one table, put the chips in my car and then go back and hit it again. Sometimes three times if I can time a dealers break.
A couple of times I have played at the table and said this color isn't lucky let me try another. If I need a specific color I ask for it. I say something like I was lucky with Brown last night can I have it again. Or green is my lucky color. Barry
