| Even regional differences in things. If you say "one bar of butter", "one stick of butter", and "one pat of butter", these can all refer to three different things or the same thing, depending on where you are located. East Coast and West Coast US butter are sold in different size blocks (though both are "8 tbsp") however sometimes you'll find 4tbsp sticks on the west coast that look like 1/2 an East Coast stick that I've heard called pats. Then Europe comes along and all the fancy European butters are made in 250g blocks, which are bigger than the 110g sticks but smaller than the package of 4 of them! This always confused my European friends when I'd say "oh I'll toss in a stick of butter" because they thought I was adding a quarter kilo of butter. |
I can't guarantee that the sticks don't exist anywhere, but I've lived in several cities all over the country and I've never spotted anything like that
