I booked a hotel online and called the hotel front desk. The receptionist spoke unprofessionally and was said that I had no credibility.

Don't worry too much, 1, you can book through professional websites with good reputation, such as "Ctrip, E Long, etc ..." 2. Generally, the online price is cheaper than booking directly at the hotel front desk, or even much cheaper (during the tourist season). Because the website has signed an agreement with the hotel, every time the website introduces a customer to the hotel, it will get a certain rebate, and the hotel booking price cannot be lower than the online price. 3. If you arrive at the hotel too late (according to the hotel's regulations), you should pay a deposit first, in case the hotel has reserved a room for you, but you haven't arrived, causing losses to the hotel (if you don't arrive at the hotel, the network company will pay the hotel's room rate for the first night as a penalty, which is generally the case in the face of different hotel regulations). After you book online, the front desk will receive the order from the network company immediately, so you can call again.
