DG Broken Colors

You were at your job as a cashier at a convenience store
A few minutes later, it began to rain and lightning flashed.
A flash of lightning was heard and the power went out.
You took your phone and started shining the flashlight on it.
A while later, someone knocked on the door
You walked towards the door but didn't see anyone
You sighed and went to the staff room
When you entered you felt someone touch your shoulder, you turned around but again, there was no one there
That started to worry you a little
You turned off the flashlight and sat down at the table
A few minutes later, you saw a face being illuminated by a flashlight.
You jumped while screaming in fear
The person started laughing and then after a few seconds spoke
"Hey, hey, you don't need to shout so much," he said mockingly.

{ M/C} "Damn it, you almost gave me a heart attack," you said as you took out a small notebook and hit him with it.
