Submarine sandwiches are helping to save lives. Customers of Firehouse Subs helped fund a grant for the Kentucky 86 Fire and Rescue department in Elizabethtown. It paid for more than $24,000 worth of equipment to outfit junior firefighters for training. Each restaurant allows customers to "round up" their bill to the nearest dollar, and donate spare change to the Firehouse Subs' foundation. Firefighters and franchisees thanked the community for their support on Wednesday.
