Fence, meet post.
@xmanmonk it's not wrong if the values on top are zero-indexed, but I don't think that's the case here.
@dbucklin True, if the values on top are zero-indexed, and the value on bottom is not (since it's a count), but the second value on top should also be a count. So the only way it's right is if they're inconsistently indexed. Or if an item was added after the first line was printed but before the second line was printed. Or alternate universe stuff. That could always happen. Especially at a Starbucks.
