Steak 'n Shake review: wait staff and management

When i'm with my pregnant friend. As soon as we sat down the waitress was very rude for absolutely no reason. We asked he a question about the menu she didn't even acknowledge us just had a smerk on her face then was very rude and short answering our question. I can't explain how horrible she was treating us. Then when I asked for he manager they were all back there laughing and didn't want to do anything about it. So we left and didn't order anything. I never had such horrible customer service and for that waitress to be so rude for no reason blows my mind.
