Well, of course they're not fucking. They're dead.
If you have a severe seafood allergy, like redditor rick_RAWS, you want to feel confident that your server conveyed that information to the chef in a clear and insistent way. Preferably verbally. And then perhaps confirmed the absence of shrimp a second time before bringing out the food to you. But barring that, this death warning is pretty straightforward. Considering rick_RAWS managed to post it to reddit, I'm guessing it did the trick.
Mmm...now I'm craving Chick SS.
