At the local bowling alley the two pins more often then not say 1/2 credits, i have seen young kids put in a quarter and walk away thinking its broken because everything else there is a quarter play, and i don't know if they get it that its fifty cents to play. Its a nice added bonus to come up to a pin and see a 1/2 credit, i usually end up putting in a couple bucks anyway, so its like a drug dealer given me a little bit for free. then im hooked.
