It sounds like an in the middle of nowhere type of scenario where the gas station is the closest bathroom... Why complain that a gas station is far away when you have to poop if there's a bar closer by? There must not be. Math.
TWD is about survival to me. Hard choices and such in a world that has a lot more hard choices for the characters to make. I just thought it was interesting that both of the teenage characters died and they didn't bother to set up at least a third who lived through Thanos's finger snap of infinity or wtf ever.
They only killed him off because he's a teenager in the reboot they made for the Avengers. They set Groot up as a teenager and killed him off too. It's like they're trying to scare the younger generation into keeping their heads down.
