@Rasz I was like that too, until it was just too much work to pick out all the small rib bones and I was like eh, F it, and just chewed through them and it was fine.
When you eat whole fish such as on a stick like this it's easy to avoid the main bones while leaving most of the ribs attached to the spine, so just crunch through the small ribs that happen to detach, it's not a big deal and is way less hassle
