Copy Or Teleport, Dead Or Alive(8)

I should ask for help from the staff at the station, they are professional.
Ten meters away from me is a station worker in a black uniform. "Excuse me, sir, I think I'm in trouble, the transient device is malfunctioning." Without any reply, he just leaded me to the control room.
I saw no one else in the control room, and asked him cautiously: "Do I need to wait here for a while?" Finally his lips moved: “I think so, maybe the dispatcher went to pour coffee.” Before the words were over, another man in white overalls came in.

“Oh boy, do you need any help?” He walked to the console, sat down, and didn't look back at me. “Obviously, yes. A transient device is not working.” I replied, and he continues: “Did you forget to pay three tak? Or you forgot to enter the destination and forgot to authorize the transient device to start?” “That’s impossible and ridiculous, sir.” I’m a little worried and impatient: “Every Monday to Friday, I will go back and forth between Chongqing and Shanghai because I need to go to school, just for this month, I have used the transient device thirty times. I can’t make such a stupid mistake. There is something wrong with this device. ”
