Obviously you shouldn't smash lobsters, or any living thing against the wall for no reason, that's cruel as fuck. Though, the shittiest thing in that video is that Prawn Showers busted out the display glass and smashed up all the merchandise. Some little Chinese guy probably got fucked over big time that month, BUT OH NO THE LOBSTERS THINK OF THE LOBSTERS!
I used to spear lobsters for a living and they spend most of their lives sitting under a rock eating waste, they're fucking cockroaches. I can't speak on humane prep for spiny tail lobsters, being as they have usually already been speared thru the head and you just grill the tail, but my hippie uncle severs the brain stem of Maine lobsters before steaming.
