Which country, which industry doesn't have a gray chain of interest?
...
Albo Biological Company's blood station.
A black man wearing a large gold chain walked into the blood station, looked around, and leisurely made his way to the reception desk.
The receptionist, a middle-aged Caucasian woman, glanced at the black man, her eyes fixed on his thick gold chain; she felt he didn't look like he was there to sell blood, "What do you need?"
"I need to see your station manager."
"Our station manager isn't here, do you have business with him?"
"I just called him, and he asked me to come."
The Caucasian receptionist counter-asked, "Are you Garcia Roger?"
"I prefer to be called 'Blood Man' Garcia."
The Caucasian woman shrugged, "Room at the end of the left corridor, he's waiting for you."
Garcia's nickname sounded intimidating and he indeed ran a blood station, but it was small scale, no match for a large company like Albo Biological.
"Knock knock."
"Come in."
