it actually doesn't have any use.
No, not even close. The vermiform appendix, in animals that have one, is most likely a storage spot for the "good" bacteria that help you digest food. The idea is that, if you get bad diarrhoea (the 'runs') and your "good" bacteria are flushed out of the body, then the appendix will release its stored bacteria, allowing your gut to start digesting food, again.
It will help in digesting the food, if you chew it well.

Our teeth chew up our food to make it smaller and get all the nutrients, so that it is easier to digest.
Saliva/spit grosses out grown-ups. They also help on digesting your food.
Food only passes through your stomach and intestines not the appendix.
