In a four-star hotel, can I ask the waiter to help me wash my clothes?

Four-star hotels can't ask hotel attendants to help with laundry, but they can entrust the hotel laundry department. Generally, hotels have laundry departments, but there is a charge. You can also wash it yourself. There is a rack for drying clothes in the bathroom. Washing powder can be bought at the front desk or any convenience store.
