In passenger transportation services, if the interior of the vehicle is contaminated or soiled by customers due to food, drink spillage, vomiting or other behaviors, professional cleaning is required to restore the vehicle's clean and sanitary condition. Since the cleaning cost is affected by many factors such as the degree of pollution, cleaning method, required cleaning materials and time, etc., we cannot provide a fixed cleaning cost standard in advance: the actual cleaning cost will be based on the actual pollution of the vehicle and the difficulty of cleaning on site. The specific situation will be evaluated. During the passenger transport service, if the customer's improper operation causes damage to the in-car facilities, such as curtains, safety buckles, cup holders, etc., the driver will make a determination after evaluating the specific situation on site.
