I'm no expert on a lot of things, as you have seen by how I handle most subject matter in this article, and the British pound is no exception. I'm no expert on foreign currency in general, unless you count arcade tokens as foreign currency. The exchange rate on them is pretty easy. One quarter of US currency equals one token. That never changes, thankful. Even with my lack of foreign currency knowledge, this doesn't seem right. Math has taught me that half of anything is always... half. Not only is this not half, it's more than the original value. Any mathematician could see the problem here.
British chocolate is better than American chocolate though, so maybe it's still worth it. I don't like it on principle, but I'll gladly pay more for better chocolate.
