True story..............
Years ago, across the street from the T&T in Surrey was a restaurant called the Oriental Buffet. One of the dishes they offered was crab legs. The legs were definately Dungeness crab which were obviously undersized.
That year I was doing a lot of crabbing, fishing and camping on the Tsawwassen ferry jetty every weekend, (overnight camping was allowed then) anyways, almost every crab I caught that year had only one claw????
After the lunch at the Oriental Buffet I knew where all the missing claws were going.
