Jersey Mike's Subs

Celiac beware!! Ordered a gluten free sub for an allergy. Watched them fry the meat on the same grill they were toasting buns. When I asked them about it the "lead" guy denied it. I stated that I just watched you do it. He said " this is the first bread on the grill today", this was was at 1pm. I asked again so you never put any other bread on that grill? He stated "we clean it after every sandwich" and " I don't understand the process because NO one has ever been sick with his way of doing it." I asked if he knew the difference between gluten-free and Celiac disease. He refunded the money. Place wasn't clean and all three workers were rude to each customer prior to us.
