This question already has an answer here:
When John Ruth enters the cabin in The Hateful Eight he tries the coffee, he reacts, immediately spitting out the coffee and throwing it on the floor complaining about how awful it is.
I'm not sure about this scene, to my knowledge it was Minnie who made the coffee. According to four-horse Judy, Minnie's coffee is supposed to be pretty good.
For the record, I've seen: How come the coffee initially tasted awful? But I am under the impression that we know Minnie made the coffee.
Why does John Ruth dislike the coffee so much even though it's supposed to be good?
EDIT: My question is different, why does John Ruth dislike the coffee and complain about it in the beginning scenes? As one user brought up... it might be a cross-reference to another movie (not mentioned on the other thread). I'm starting to think it's possible an answer might be provided with some evidence to support this.
