You are totally incorrect for reasons already stated.
My error, had to run to meet someone and did not post properly. Should have stated with your comment " WITHOUT A FUCKING PENNY FROM YOU ".
He is paying for the service which should include clean sheets, it is part of business as some people only do incall and you need to cater to these people. The room is paid for by Mike and if the guest did not book it would be a loss of money. In theory the girl should have more business and in cases they probably do so the cost is absorbed. And with the outcall girls extending their shifts if work is available why can the incall not do the same. In an incall I do expect clean sheets when I enter the room and the girl should have time to shower and clean up. What Mike is doing is good business by providing both services and his prices are good.
