We've been using a Lego/Duplo box to knock out the pucks. It's fun, cheap, and a conversation piece! When it's full, we close it up and making it easy to carry home to the garden. (or we can fill it up for customers)
:grin:
I used a hollowed out manequin head for several years. Helped oodles with tips and I could always picture the face of the last customer there when I became irritated. Also fun to cut out and post pictures of your least favorite Republican over the face.
