Steak 'n Shake review: service

I waited 10 minutes to be seated, I was the only one waiting to be seated and all the workers just totally ignored me. When I finally got seated the waitress that seated me in her section, then she seated another customer and waited on them before waiting on me. Finally after 10 minutes she waited on me, I asked for the manager and I was told the manager was too busy at the moment. With this kind of service how do they expect to stay in business? This was the worst experience I have ever had at Steak N Shake.
