How does a hotel doorman provide car door services correctly?

When the guest's car approaches, the bellman gestures to the driver in the driveway so that the car can be parked in the appropriate location. After the car has stopped, he quickly runs to the best position to open the door. Greet guests warmly, open the car door to welcome guests, open the front door first, then the back door, open the car door with your left hand, and protect the roof with your right hand (except for Thai, Indian, and Islamic guests). Then stand at the back door to serve the guest. If the guest takes a taxi, count the number of luggage with the guest, record the license plate on the hotel taxi card and hand it to the guest.
