Clack as the deadbolts lock.
Beep, beep, as the alarm sets.
Then the bank is overcome by silence.
He drowns the squishy sounds of his mop with 90's grunge.
Walls echo as he sings aloud,
"Times are gone for honest men."
Thunder overtakes the music.
Pause button clicks.
Did he hear the doors unlock?
The bank is calm, outside chaos.
He must be hearing things.
Play button clicks again.
"Black hole sun, won't you come."
Deafening thunder shakes.
Hum of power dissipates.
Footsteps are now clear.
Louder and louder.
Then a woman says,
"Come with me or you will die."
