What should I do if the front desk of the hotel is abused by the guests because of the room price? Online, etc

First of all, the room rate is the unified pricing of the hotel. Employees have no right to modify the price and need to explain it to the guests.

Secondly, when the general guests insult the house price, they don't specifically target your front desk, so there is no need to scold you.

Finally, for unruly and unreasonable guests, you can choose to be silent first, and then explain the reason or the value of the house to him when he calms down. If the guest is really rude, you can ask the hotel security to protect the personal safety of the front desk staff.
