This is the worst of the Firehouse Subs that I’ve been to. I asked for the packet of mayonnaise to be put on the sandwich instead of a packet in the bag. They said they couldn’t do it because the gluten free bread would cause a problem. I said that’s ok all the other Firehouse Subs do it. She said “I’m sorry, we just can’t do that”. I cancelled the sandwich and have no plans to return, and I live in Oak Ridge. The best FH is in Hardin Valley. Great customer service, great food, and worth the drive.
