I worked as a cashier at a riverboat casino in the midwest. Some nights I would be in the little cage in the high limit slot area. About once a month a specific woman would come in and take a whole row of the $10 and $25 slots (around 10 machines) and just walk up and down the row putting coins in the machine, hitting the button, and moving on to the next machine without even waiting to see if she won.
