Jon Alexis, the shameless self-promoter of TJs Seafood Market, is standing behind my desk holding a jumbo-sized stone crab claw to my head. ‘”Listen to me,” he says. “We now that we have two stores, we have serious buying power.” He pokes the claw deep into the back of my neck. “Now I’m able to leap over a vendor and get them FedExed directly from the boats. Now put that up on SideDish.” Jeezy Pete, this guy is turning into the mahi-mahi mafia.
