Wouldn't there be another ramen shop that was more principled/greedy to the point where they'll allow service for Faunus if it means more profits? I mean, something like the public drinking fountains law enacted by the government might make the Fang more believable. True. Though, there's still the mere fact that business are even allowed to discriminate in that way, which is unfair to Faunus. And what if that guy's ramen shop is cheaper than the other ones and is well-known for some really delicious ramen? Faunus miss out on that because he won't serve them, and the reason he doesn't serve them is something as stupid as "You're a Faunus".

As for the Grimm feeding thing...

I don't recall it ever being said that they feed on negative emotions, just that they're drawn to negative emotions.

When it comes to eating people, they haven't said that they need to feed on people's flesh. From WoR: Grimm: "In fact, the common belief is that the Grimm are not obligated to feed; they choose to."

So, the reason that Grimm die when they're caged is still anyone's guess, but it's probably not starvation.
