So if that's a thing you only do every once in a while, you are a prime candidate for confusing advertising. You don't already know what the thing you want looks like, and you probably weren't expecting the ambiguity, because "meat" has meant one thing for thousands of years.
But yeah, that's why said it less of an argument, more of a fun fact. I honestly couldn't tell you if the regular supermarket I usually shop at has patties, I think not. The large one usually has everything though.
That's super funny that you wrote that because actually "meat" comes from Old English "mete" which referred to food in general.
