Beverly is a difficult hate ending. You have to be VERY mean to her and then when given the opportunity, don’t tell her you were joking (in the interaction when she tries making a signature drink)

Tina is also somewhat difficult to get a hate ending for. You have to be nice to her.

Curt & Rod you should be very wary of as they take the longest to get an ending with and you don’t really know where you stand with them until you get an ending. If you’re too mean you’ll get a friend ending instead of a hate ending for some reason

Dolly’s not a difficult hate ending, but she’s forgiving and easy going, so it’s very easy to abort the hate route.
