At my Center we have Sensior league Monday thru Friday usually at 1pm. There usually big leagues taking majority of the center. One of my former team mates bowl in one on thursday. They get free lottery drawings, 10 free games a month, monthly birthday cakes, free coffee, and free shirts.

I also remember when i was junior i helped volunteer for bumper leagues parents use those to drop off there kids for about 1 hour and come back and pick them up. I remember seeing kids there and there parents were no where to be found until around the last game they bowled two games.
