Gambling on the slot machines is fun, especially when you can get paid without getting up (see the sign on the empty row). At all times of the day, people, looking very bored, stare at a screen and press a button. The typical profile is of someone older, possibly retired, usually female, a little fat, dressed in Target clothes. Forget the glamour. Casinos know where the money is, and it is not in the small and select group of high rollers.
