Can customers bring their own drinks when they go to the hotel to eat and drink?

It depends on the hotel. Some hotels explicitly prohibit bringing their own drinks, but others don't care. Personally, I think it's inappropriate for this hotel to prohibit bringing their own drinks. You don't have to buy your drinks when you eat at your house. Besides, the drinks in hotels are generally more expensive than those sold outside, just want to make another profit from the middle.
