Using a Gambling System

A reader asked the following question: "I have never been to a casino before. I have a hedge betting strategy/system that I want to try out. In an online chat room someone told me that ALL systems in a casino are not allowed. I responded by saying that I thought only people who count cards in black jack get banned. This person went on to tell me that they are pretty sure that if I am at a Roulette table long enough using my system that I will be asked to leave. Is this true?" Read my answer.
