After reading the manga and the translated WN, I can't help but feel that MC is a little too stingy.
I get that he wants to set reasonable expectations and his "customers" seem satisfied with what he's been giving, but surely he can do a little better? He still thinks and acts like a grouchy cheapskate despite his relationships with the gods and his familiars being massively tilted in his favor.
I don't know, maybe I'm just a spoiled little bitch, but I find his attitude unpalatable.
