Why is there no washing machine in the hotel? Do your own laundry every time you check in. . The hotel doesn't even provide washing powder? Why are you so bad at business?

I think you have overlooked a problem: you are definitely not the only one who washes your clothes in the hotel. Don't so many people feel dirty washing clothes together? Aren't you afraid of being infected? There is nothing wrong with washing, it is not clean, and it is dyed (clothes are easy to dye), so you can't fight with others? Therefore, it is understandable that hotels can't go looking for trouble and provide such services. If necessary, paid services are generally provided, which can reduce the number of laundry and ensure the quality of laundry.

I don't know if you accept this explanation.
