Steak 'n Shake review: drive thru

The wait time at steak n shake was unacceptable. I waited in drive thru for over 35 minutes. Service was extremely slow on 4/6. This is unacceptable service! Lastly the workers was giving out incorrect orders. Absolutely no organization. I have never had an experience like this from steak n shake. I'm upset at myself for waiting such a long period of time for drive thru food.
