This day, about 22 o'clock in the evening, as usual, I was on the floor. At this time, the big brother of the intercom agency suddenly called me: "Manager Liu, trouble to the next floor!" Later I realized that it was Tie Chengge who asked who is on duty today? So Guan Da Ge called me down the stairs. I trotting from the passage to the first floor, just arrived at the elevator door of the hall, I met Tie Chengge. Big Brother saw me smile and said: "Yaozhong, what is the name of the security brother who is on duty at the door?" I looked at the door and said, "This is the big brother of the Ministry of Security Guan Daofeng!" Tie Chengge said with a thumbs up: "Service Very good, remember! When I came, he ran to the door and pulled the door to help me down. I said you know me? He said that he knows handsome guys!" Then I knew what was going on. Big Brother added: "He doesn't know me, indicating that he often does this service. Our service industry is doing this! Now it is not a good service for young people, it is not necessarily!" I quickly said: "Yes, Tiecheng Brother, the service industry service is not limited by age." Big brother smiled and went to the room and once again stressed that he would praise the security brother!
