It will be fun. Besides, free accomodations are a good thing. And, it will be a bit difficult to burn. My ultimate plan is to allow those who don't have enough money for the services to pay with a slight, temporary drain on their lifeforce. I can, over a significant time, charge life crystals. I go back to my fortress and create a 1-story room directly inside the gate, with a bar and several more tables and chairs. I try to enchant it with a light and fire cantrip to make it warm and bright enough to be comfortable. The room is midsized, about the size of a regular bar, and has a door behind the bar opening to the rest of the fortress.
