A loaf of bread is consumed.
You break of a section of a combi bar and end up with separate bars for the rest of the story.
And if silver would become the 'future currency' of most people, then a maple will buy 2 loafs instead of 1.
If you were a baker, would you give 2 loafs instead of 1, just because of the... ehm.. broken off part of combi bar element? If I were the baker, I'd give one of yesterdays leftovers haha.
