Put in one dollar, and press the one line and one unit per line buttons, and away you go, spinning for a penny. Some machines do not let you do this, but most do. You can play most penny slots for just a penny a spin. So you are essentially paying $1 per drink (or you are being a jerk by stiffing the cocktail waitress, who works hard for below-minimum wage). It is considered rude not to tip her $1 for her service. The cocktail waitress will provide drink service to the people playing penny slots.
