Is the hotel ice charge legal?

This is illegal. Now the hotel doesn't stipulate the charge for Chinese ice cubes. Generally, it is provided to guests free of charge. The room attendant will remind you unless it is used in the guest room. It has something to do with the grade of the hotel. Don't think that the higher the star rating, the more expensive it may be. In fact, on the contrary, the higher the star rating, many secondary services are free. Such as tea, ice cubes, wet towels, tableware replacement, including spices and the like. Five-star hotels and three-star hotels, among which etiquette services and free items are definitely five-star hotels.
