Two of the Arkham Encounter cards from CotDP have wording that makes me question their meaning:
The first is at the Hibb's Roadhouse location: it starts ""Friendly game of pool?"", the second result on the table contains the phrase - "If you confront him" then goes on to give the result of confronting the cheater, does this mean you can decide to not confront him and receive neither the bad nor the good effects?
This question actually applies to other cards that have the phrase "you may" and have both good and bad effects.
The second case takes place at the Black Cave location: it starts "A monster surprises you" then goes on to describe what benefit you receive depending on whether you succeed at the Horror Check of the battle or not. What happens if you encounter a monster that requires no Horror Check, such as a Cultist?
Thanks for your help in advance
