There are different souls that one person makes to suit their personality. When you cut up food or make your own food, it is your personality shining up to give to others.
I mean when you are cutting up vegetables in a normal manner, the vegetables are reflected towards your personality. Even if you cook at home, you can taste your personality depending on if you want to make it taste better or not. This would be similar to cannibalism but you are actually not eating another fellow human being but eating your own soul.
When you go to other businesses, you are eating their personalities which sometimes make you come back for more is similar to eating their souls.
There is a quote on food “food is the way to the soul” or something like that.
