I've tried to like kneaders because everyone talks about it like crazy, but every single time I go I leave unsatisfied and I tell myself I won't come back. The first time I went I found a hair in my sandwich. I understand that things like that happen all the time, but it turned me off. Another time I went I ordered a sandwich and the bread was torn in half making it very difficult to eat. I am just not satisfied with the customer service either. When I have a problem with my meal I feel as though I am a nuisance. I shouldn't feel like that at a restaurant. I will not be going back to kneaders.
