What is the job of a hotel sleeper? Do they have to pay for staying in a hotel?

The sleepy man at nine o'clock is an employee of a company. Their job is to stay in these big hotels around the world, and the expenses are paid by the company. They want to experience the comfort of the hotel, such as the quality of the bed, the comfort of the room layout, the convenience of the bathroom and so on.
