Steak 'n Shake review: service

In the past few months every time I visit the DeKalb Illinois location we are either greeted with signs at the door saying closed, after entering being told sorry no inside orders, or sitting inside the restaurant for 30 plus minutes before being seen by a waitress or waiter walking out. The service at night is awful and needs to be addressed. Either post signage stated closed at night Or find people who will serve to customers at night. I'm kind of tired of wasting my time trying to give my business to you when you clearly don't want it
