Before checking out was asked to leave cards keys in apartment. So I told receptionist how will I exit if I don't have card key and said I had to go back to my room take the card key from my room. Then I will be able to exit premises but he also said that I will be charged for taking the card key. Also he said that's how they make extra money by charging for the taken card key. His words not mine so I was like how absurd.
