There is no parking lot in the hotel itself, which was explained when the front desk opened, but the guest's car was scratched outside. What should the front desk do?

Ask the guests if they need to call the police, and help them call the police if necessary. Otherwise, everything the guests say is "I'm sorry, we'll try our best to help you solve it."

If the guest is determined, please ask other colleagues in the hotel to call the police in the office and ask the police to take the guest to the police station for questioning.
