My room mate don't have a car, and these past few months, I’ve been driving him to work because his work is just nearby. But the issue here is that, he never offers gas money, or even say thank you, and sometimes makes me late by taking his time. So i told him I can’t keep being his free taxi, and suddenly he blew up on me. Never again ride with me and he never even talk to me. I don’t know why he got mad, I'm just saying that maybe he could offer some gas money for the ride or even maybe say thank you for dropping him on his work. So AITA for the not giving my room mate a ride anymore?
