To clean the store, shelves, etc...scrub it all down.
If they’re cleaning CV off the baby formula then where’s the hazmat suits?
The neighbor, who’d gotten off work, called about 25 minutes ago all in a tizzy over it being closed and no cars in the parking lot. She didn’t know about the new hours.
Either they needed all night to clean in secret or aliens abducted them or they all walked to work today. I’m going with the aliens.
