Paxboy,
You try eating a lobster that has been 'dead' at time of purchase then transported for goodness knows how long on an aircraft, then into your car and back to your home.. I doubt you'd eat lobster again!!! Lobsters and Crabs 'spoil' easily and therefore have to be transported live or Frozen and indeed if you do buy them dead (From the Fishmongers for instance) you must cook them soon after purchase i.e. within a few hours. Not only for hygeine and health reasons, but also for flavour. Sorry, but it's the truth.
