How do you gently and professionally reject a coworkers advances?

Anonymous
Hi, I'm socially awkward and a coworker tried to ask me out for lunch tomorrow at the end of my shift tonight. I said no to the place he asked to go to and then practically bolted out the door to my car before he could ask anything else. I feel pretty bad about it but I'm not really interested and struggle with social anxiety. I'm pretty shit at rejecting people and need some pointers. I really don't want to hurt this dudes feelings and would like to keep this professional.
