We were always very careful when we were in the hostel and didn't use the kitchen. However, after we checked out and left, because of an old smudge on the table and the hoster had some misunderstandings, the hoster sent a massge for compensation after we left. We tried to call him, but the hoster refused to communicate. In the end, I could only sned a message to tell him that this smudge has nothing to do with us.
