Go bowling for Love's sake

During every bowl game, prove allegiance to one of the teams (wear school apparel; dust off your library card) and get half off the Shack's signature jalapeno-cucumber margs, plus, because the resto's mostly patio, the use of a Shack-branded leopard-print Snuggie, strategic as cheetah Snuggies would only encourage dine-n-dashing, at up to 70mph!
