Denny's review: Service

I ordered online and was informed my food would be ready at appx. 212am. At that time I arrived and was asked to sit down. Another waitress later came to check on the table next to me but only looked at me and left. Later when she came to assist other tables, she asked what I wanted. I informed her that my food should be ready as I had pre ordered. She stated that I could not eat here (at the restaurant). I reminded her that I could not eat anywhere as my food was still not ready. She later brought me my food and as it was missing items, she gathered them, but only after checking on other people. The food was horrible. Cold fries. And a soggy cold burger. And all other food was cold as well.
As I ate my meal, she made sure to frequently check on all other tables except for mine.
