我該不該付這個費？多謝了。（沒多少錢，隻是覺得不合理）

The manager told me that if you clean the apt, the cleaning fee will be $45 for the carpet, then I cleaned everything which was better than before I moved in. Then she charged me $100 because she thought the two "windows" are NOT clean enough. I asked for the receipt of the cleaning, she told me that the windows are cleaned by the staff working for the apartments. She has no receipt.the fee will be $55 even for the two windows.any suggestions are welcome. thanks a lot.
