Leaving work early on a slow day? 🌝

Hi all!

Im a pharmacy tech for a small, privately owned pharmacy and for the past 3 days with the holiday (I work in an area with a large Jewish population), work has been verrryyyy slow.

I‘ve already asked my manager/pharmacist if there is any busy-work or anything I can do, to which they responded ”no.”

Is it frowned upon to leave work early on an extremely slow day? I’m an hourly worker.
