Steak 'n Shake review: service/hours/ unprofessional staff or just manners

In Noblesville Indiana the location.. when they decide to close they are very rude when they inform over the drive thru intercom, they close the lobby with a 24 hours open sign still up. I have went to drive thru at 4:20am after working 3rd shift and told it would be 15 minutes before I could place and order.. with no cars in front or behind me. This location the staff they do have is very rude and unprofessional! Consider bringing in other staff or close the location like nearby cities have due to no staff. Must be something wrong with the company for various locations closing due to staffing issues.
