This isn't a Town, It's the Capital! It's a surprise to MC and the Girls since they never ran into such BLUNT racism!
Starting of course with the Guard at the gate! Though they didn't get the worse of it because Gramps, someone EVERYONE knows not to fuck with, was with them (and if they don't, his killing intent is enough to terrify a racists into "keeping their thoughts and feelings to them fucking selves)
If he had been there and saw that, he'd have likely just got them to leave before the blunt bad behavior showed up! No need or wish to expect good decent services from fucking Racists. Better would be if Gramps influence with his fellow Adventurers meant he convinces them to not do services with the Racists, cutting a SHIT TON of money spending Customers to them in the process! But seeing how PRETTY MUCH ALL of them denied services. It's very likely that would not be as effective since it's largely the entire Capital, so that would hurt THEM then it would the business!
MC will likely have to find something to cheer the girls up (and not let gramps know least he does something "Regrettable" as they still have to use the place as a Hub! Though one would be somewhat glad at least they got "punished for Racism") MC just needs to be mindful the discrimination is alot more prominent around here to avoid the girls having to experience that shit show again (Annoyingly they have the right to refuse service unfortunately, and the setting means "anti-discrimination" laws aren't even a THOUGHT in ones mind! The first place can fuck itself cause at least the others were BLUNT in no service, while he just tried to PRETEND they were filled up and got humiliated abit when his lie was easily disproven just as he said it LOL before he told them no service go away! So he looked more like a dweeb then if he had just been blunt from the start!)
I mean they are good at making alternatives after all! It's what started the story when the Local Lord's loser son took over and cut funding and supplies to the Orphanage, WARRENTING MC to use his "modern mind" to make them self-sufficient (as who would trust a service where if the one who did so passes or gives control to a loser son trying to "save" money to abuse and waste himself. Better to have your own shit), and now they know it likely is a GOOD idea to be with Gramps when trying to get services if with their "non-human comrades" (or better NOT too and MC deals with things, his advantage here is being human, they aren't going to second look and mistreat him. just don't do business with Racists then!)
