Communication between the Game Master and the players is crucial to keeping the game fun. Solicit feedback from your players from time to time and see how they feel about the experience.

Sadly, there isn’t much you can do about this, unless you want to give them their way. And honestly, what’s the fun in being the GM if you’re just going to let players have their way?
