It cost you nothing but time and some supplies. If you asked a random person to clean it, they would refuse. So you have to pay them. Minimums for cleaning would be 3 hours. At 50 an hour plus taxes and travel $200 doesn't sound unreasonable.
If you can't efficiently get cleaning services for your rented out room, maybe you should get out of the hotel business!
But those paying cash, no taxes, low salary abusing people, should remain in business?
What an insane take.
