Complaint about 15:10 noon on August 6, 2020, the security guard at the door of Qinghai Science and Technology Museum on duty, with a bad attitude. We did not find 1,000 tourists a day on the official website and Trip.com search. After we arrived, our sister patiently communicated with the security guard and said that the security guard agreed to enter a few more people (this security guard right is quite big). Later, we went to the door and the door was closed. My sister is already in the hall. We opened the door for us, so the security guard pointed at my sister and shouted at her, and pushed her with his hand, and said out loud: "You give me out, who let you open the door"; I was blindfolded. I didn’t know that I couldn’t go in before entering the door. When I entered the door, I heard the security guard pushing my sister and yelling at me: “You give me out, go out, who let you in”. I am also in the travel industry. I deeply understand that my sister is wrong to open the door. But the security seriously violates the basic literacy of the tourist staff, he can say "sorry for the full today, please go out, you can make an appointment for tomorrow's visit", this way I think every tourist can accept, a small behavior of the security guard affects a place tourism Image, we called before coming, and did not inform us that today is full, or only receive 1,000 tourists a day, only after the phone call, came to encounter malicious security, I also seriously criticized my sister behind, reprimanded her should not open the door without permission, I also reflect on myself, but I deeply hope that Qinghai Tourism Bureau and Qinghai Science and Technology Museum will do a good job in training employees in the tourism industry and educate and train the security guard. We believe that the comrade is only a matter of awareness, whether there are other faults, and the temporary contact is not understood. Tourists and friends from all over the country and the world are coming because of their likes and yearning, and they just hope to gradually improve and do better. The picture below is the consultation phone number I dialed before I went to Qinghai Science and Technology Museum.
