There are two types of places that you'll hear the phrase "hands off my pasty!". One can get you kicked out of an establishment with a cover charge and the other is just any reputable restaurant Up North.
In Michigan, 'pasty' means something entirely different than in most parts of the country. Which is great, because I'd rather eat one than wear one. Just gotta remember to pronounce it right (pro tip: if you're talking about the food, it doesn't rhyme with 'hasty').
