Or instead of half a dozen inns there are a band of nomads settled around some wagons. And they need water or food, or there are wolves attacking them at night, or there are bandits attacking them. Do you help? And how do you help?
Inns serve no purpose other than occasionally giving you a quest. And there is no telling if said inn has a quest available unless you run across the map to find out. There should be atleast an icon indicating quest availability. Or atleast reduce the starting areas to only one inn.
Also you should be safe in an inn and creatures shouldn't be able to walk into an inn tile.
You should be able to heal up and rest at an inn. If you already can - I couldn't obviously tell.
You should be able to speak to the inn keeper and get word about new quests and passerby champions
If inns are only placeholders for quests then remove them and find a better way of questing. Like the above example.
Perhaps in this supposed "post apocalyptic world" there lays a dead champion on the ground, you walk over to him and discover a "clue" - opens up a quest.
Inns are easy and uncreative right now. But wait - we will get an editor and can do this ourselves - that's right!
