Firehouse Subs Anderson

Hubby wanted Firehouse for lunch and I am gluten-free so I looked up the website which said they have GF bread now at all US locations. Went inside, they had it on their bread options sign at the counter, but when I asked for it, they said they don’t have it. It wasn’t a “we are out”, but “we do t have Gluten Free.” I definitely understand that not all businesses cater to those with allergen specific needs, but please don’t advertise it if you don’t carry it.
