Faerin for the Guests giving their opinion it is just weird to see them enthousiastic first and then get angry about it.
For that you can change it this way.
Example. Guest asks for Indian food..you pick the right one..yes that's definitely Indian food. Let's try it. Followed by the opinion of the guest for the food quality.
Drinks: Guest asks for something with Vodka in it. you pick the right one..I can smell the Vodka all right..Let's try it. Followed by the opinion of the guest for the drink quality.
Fitness: Guest want to work on lats. you pick the right one..I felt my lats all right..it was good or but not in the good way..
Sauna: Guest want moderate with low humidity..you pick the right one. the type of sauna is what I wanted..but I feel awful..and I feel great.
Club Dancing: Guest wants French dance..you pick the right one..I recognized the French style..but it was poorly executed..and it looked fantastic.
Consider these hints as I believe it will really add something to the fun to play.
If you need some ideas for the other categories..let me know.
