I have never had a casino. I’ve heard of casinos and I’ve read about them but I have no idea what they are.
Casino and whatnot have always been called gambling machines.
In all honesty, I couldn’t tell you what casinos are unless I had seen one first. If you are going to ask me what casino is, you will probably have to explain that you are, in fact, going to have to say a few different things. The first one that comes to my mind is the one that you saw me play in. I have no idea how you can play with a slot machine. I have no idea what a slot machine is.
