Person A orders a pizza

Person A orders a pizza.
Person B asks person A for a slice of the pizza.
Person A refuses, eats the whole pizza by himself.

Who is the greedy person in this scenario?

B. Order your own fucking pizza.

A. Fatasses don't deserves human rights.

If it was a personal or a regular, B is greedy. Large or above you can spare a slice for a friend.

Not just some random though

Millennials were a mistake.

I want person C to shit in my mouth.

>person A

Not a millenial and my stance is hard. The scale of the situation is important, as is the interpersonal relationship.

one slice is OK, not need to order your own pizza.

but if you wants a second slice you should've thought that through before, you can lick the plate but you sure as hell don't get another slice.

Need more context to justify your loaded question.
