United Kingdom, London, a certain hospital.
A hospital cleaner, pushing a small trolley, passed through the corridor. Ahead, in front of a ward, a white policeman sat at the door, overweight, with a gun at his waist, looking down at a newspaper.
The cleaner lifted his eyes to glance at the white policeman, then lowered his head, pretending to be indifferent, and continued pushing the trolley forward.
The white policeman heard the noise now, put down the newspaper, and lifted his eyes to look at the cleaner. The cleaner had already lowered his head and did not attract the policeman's attention.
Seeing that it was just a cleaner, the white policeman didn't care and picked up the newspaper again, preparing to read.
But the cleaner came to the ward guarded by the policeman and suddenly stopped, seemingly peeking into the ward.
The white policeman felt a bit impatient and was about to remind the cleaner there was no need to clean, telling him to hurry and leave.
