Greetings all
I just GM'd my first rpg ever last night and of course it was Dungeon World. I played with a group who had expectations set by D&D and Pathfinder type games. The problem was they kept trying to do things that have rules in more crunchy games, but not so much in Dungeon World.
This lead to some issues.

My Paladin kept trying to do non-weapon based combat moves ie shield bash
My Fighter kept getting frustrated about the questions in discern realities.
All of the PC's kept wanting to Listen with discern realities.

The fact that I was un-prepared to handle this caused a bit of frustration. In the end I just let them roleplaying those things and considered they happened. But in the future how should I handle this?

Also is it possible/ok to give a player multiple debilitations ie 2x shaky.
