More Than One Reading From Katrina
If you're desperate to get your 20 readings done, there's a way to do it, but it requires patience. Make sure you have your character visit and get their fortune read. Make sure you do this before she closes, and then just stay in the tent until after midnight in the game. Once the game recognizes it's the next day, Katrina will act like this is your first reading. As long as you stay in the tent, you can get another fortune without her leaving.
