Save-A-Lot review: store operation hours

On October 11th 2019, I just went to this store and the hours said they closed at 10pm. Upon arriving, it was 9:30. Doors were locked, nobody inside. Visible hours shown on the building stating the opening and closing hours. As being a Assistant Store Manager, this is really unaccountable. Doors should be closed and locked right as when the store states their closing hours. Something needs to be said or something needs to be done. The District Manager or even Regional Manager should know about this.
