KFC Restaurant Escape

You had just come to this town this morning and you wanted to have your dinner at the KFC Restaurant in the town. You did have a very satisfying dinner but without realizing you fell asleep on the chair that you were sitting on. Later when you opened your eyes you found out that everyone in the restaurant was gone and even worse the exit of the restaurant was locked. You have a late night train to catch to get back home but first you will have to find a way to come out of this restaurant which is not going to be an easy task. Hopefully, your logic and reasoning come to help you.
