Ideas for a large commercial space
Anchor tenant, a local supermarket, is moving out, and leaving behind a 15,000 sqft space in a strip mall in a smaller town. Any suggestions on how to fill the space? Property manager has listed the space for awhile, with no luck. 

Owner has reached out to the Dollar Store, local brewery chapters, local hospital, etc. Debated indoor farming (except cannabis), gym, warehouse space, etc. 

Any suggestions/ideas would be appreciated.

Edit: clarification

Thank you everyone for all of your suggestions! Really appreciate you all taking the time :)
