OK, something is clearly off here. Don't you know what a berserker rage is? It's a mental state that ancient Vikings would go into that caused them to go into an uncontrollable fury. "Leaving a restaurant in a huff" is not the same damn thing. But you know what, yeah, let's go with it.

You FURIOUSLY ask the waitress for the check, but the only sound that comes out of your throat is a strangled gurgle, because, y'know, you're just SO ANGRY. Sounds sort of like "CHHASCKPLARGGH". Oops, she thinks you're choking on something! She just ran off looking for someone to administer the Heimlich maneuver. Oh well, maybe you can calm down enough to pronounce..

Oh hey, look! A real life ancient Viking! How'd he get to modern times? Was he frozen in a glacier and brought back to life? Did some ancient Rune Spell send him to modern times? Maybe two dudes jammed him into a time-travelling phone booth! While you're wondering to yourself about the unlikelihood of his appearance (and trying to unclench your throat muscles), he lifts you up out of your seat and turns you around to administer the Heimlich. It's really too bad you didn't notice the fact that he was, himself, ALSO in a berserker rage. See, it turns out he didn't really know his own strength, and caused you to hork up your internal organs when he pounded you in the gut.

MAYBE NEXT TIME YOU'LL FIND A LESS *LITERAL*
WAY TO VENT YOUR SPLEEN! TRY AGAIN!
