Is there a charge for mineral water in the hotel?

Some people accept it, others don't. Whether the hotel's mineral water is free depends on the hotel's regulations. Generally speaking, there will be 1 in the hotel mineral water. Two bottles are free to drink, and there are also individual charges. If it is free, a card with the words "free drink" will be hung on the general mineral water bottle, so that mineral water can be drunk or taken away for free. If there is no free sign, you can also ask the hotel management whether to charge.
