The regular vending machine companies had problems with people trying all sorts of tricks to get "free stuff". Everything from gluing coins to bits
of thread (pulling the coin back out), using washers, weights and bits of metal "cut outs" in the shape of coins. Some even tried making "claws"
that could be inserted through the flaps at the bottom of the machine. In the end they had to use flaps, rotating drums and hinged buckets to make it
impossible to get at at the goodies.
