It's just like those games where you guide a claw toward a plush toy in a glass box, only instead of stuffed animals, you are going for live lobsters. It costs $2 per try, and if you snag a lobster, the kitchen will fix it right up for you.
And PETA doesn't like them one little bit. Apparently never having seen the setup, veep Tracy Reiman nonetheless characterised the tanks as "filthy", and "making an abusive game out of their capture".
Of course, they go on to claim that since there's no humane way to kill lobsters, we shouldn't eat them at all.
They live, after all, for that left-est of Leftist ideals: the right to decide what you may or may not do.
At least they didn't trot out some bizarre global warming link.
