I locked the doors just in case some idiots ignored the closed sign and went back to finish picking up the blocks. I mixed up the words in the blocks and spelled "FUCK YOU" before putting them back in the tin. I next went for the broom, mop, and mop bucket. It was silent in the store besides the music loop of family friendly pop that constantly played in the background and the clank of my lifting the giant broom up to make another pass on the floor.

I was mopping my way toward the back of the store so I could put the mop and bucket back and walkout the employee exit without disturbing the clean floor when I heard footsteps. They sounded like they were just on the other aisle. Heavy boot steps. Did I forget to lock the front?

"We're closed! Come back at 9 am."

There was no response. It must have been my imagination. I went back to mopping. The sooner I finished, the sooner I could leave. I dropped the mop into the bucket and turned to roll it to the closet but out of the corner of my eye I spotted a shadow standing next to one of the displays. I whipped back around to see no one there. Okay, time to get my ass out of here. I wrung out the mop, dumped the water, and quickly locked the employee exit behind me.
