Steak 'n Shake

I went I nto my local steak n shake and Im usually greeted and seated. This morning at approximately
4:30 am I walked in and the employees were standing behind the counter by the cash register.
and I walked up and they looked at me and said nothing and continued counting money. I asked where I should sit and a waitress told me you will wait until I have time to seat you. So I waited and finally she glared at me and said well follow me.
Then she said something harsh like "I suppose I have to get you a menu now!"... I said maybe I need to contact corporate about the way Im treated
and she said go ahead, see what I care!...
I will never step foot in another steak n shake or my family.. I will tell everyone I know how rude I was treated also.. Im thinking of making signs also to warn the public.. Im not likely to forget about how I was treated as if I really did not matter at all..
