I’ve noticed in myself and in others that we get an odd little breakdown when somebody eats the food we have claimed as our own. So I did a small research of “why do people get so mad when someone eat their food?”
The bottom line, its just has a lot to do with manners, it’s the actual point taking things from you without asking. Its downright rude to do that, and it would mostly bother anyone.
