Down the Drain

My friend/co-worker and my supervisor, discussing something, not really sure what, perhaps the suction pressure of water flowing out of a 6" drain or maybe things we have found at the bottom of the tank? The nearly shirtless one is NOT the supervisor. We were draining the tank in the tank room here at Greenhead Lobster. This is done periodically to clean the tank and to catch all the stray lobsters that escaped out of the crates.
