Steak 'n Shake review: Service provided by someone claiming to be management

I was just at the US 31 and stop 11 location in Indianapolis. The female running the drivethru was first very rude, then attempted to insert my chip card into the reader 4 seperate times all times getting the error beep. The repeated attempts then locked my debit card for suspected fraud and "declined" when I said that it declined because she attempted to run in 4 times as I could both see her attempting and could hear the error beeps while attempting to hand her another card she said "I didnt try to run [censored] 4 times, [censored]." and refused to take the second card from me. I reached out my car window and laid the card onto the drive thru window, she then threw the card out the window and locked the drive thru window. I asked to speak to a manager, she claimed that she was the manager but refused to speak to me at all. I then entered the building asking for corporates number or a number I could reach her superior, which was also refused. If she is in fact a member of your management team, she needs A LOT more training on how to manage a restaurant.
