Something similar happened here years ago.
Guy had a pretty new ball that took some major damage from a pinsetter. When he complained to the owner to try to get it fixed or replaced, the owner turned and pointed out a sign behind the counter that said “You throw your ball at your own risk. If throwing you ball here causes damage, that’s not our problemâ€.
Guy instantly turns and throws his ball through the plate glass front doors, shattering a door and a large window, then turns to the owner and says “Yeah, I see what you meanâ€.
Owner just stood there a moment, shook his head and said “I guess I asked for thatâ€, then reached up on the wall and took down the sign, and ended up replacing the guys ball.
Ahhh, the good old days.
