Our family of four booked an Airbnb with my friend for a week. She told that she will take part on the accommodation expenses. Well then her friend was coming in the middle of the week and camping in a tent on the Airbnb grounds. This was all planned. When I was discussing about her paying her part she said she goes to tent as well for three nights and therefore won’t pay for those nights. She would have used our toilet and shower. I didn’t agree so the friends went to camping site. I got my money though as a sham I don’t have much money and had calculated her contribution to the total cost. She spent three days in camping site. I am not happy as she still thinks has right.
