Ebonite/Hammer does actually make a recommendation on this, or at least our regional rep does. We're having an Ebonite Demo Day this Saturday up in Connecticut, at the Old Saybrook Lanes. Our Rep(E/H) recommended a charge of
$15.00, which is what we charge. We had a Hammer Day at our other shop last month,
with 44 guys showing up. We were charged for all of the lane usage. We barely broke even, at $15 a head. We also kicked in the $15 towards the purchase price of the ball, (or 10% if that was the bigger number) - to try and make it appealing.
We realize we can't make everyone happy all of the time, but we do try...
