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.

"The foundation is so wonderful in that almost 90 cents of every dollar we help raise actually goes to you guys -- not administrative fees, doesn't go to corporate bills -- it goes to what it needs to go to, and that's a big deal for us," said Sarah Little, a franchisee. 

Now, thanks to a $148k grant, Barrett Township Volunteer Fire Company is hopeful they will see those renovations completed by next spring.  

“This is huge, we have a 30-year-old building. A lot of the guys here, including myself, put a lot of sweat and tears into the building. So for it to be improved and going this route is going to be a big thing for us,” Cleveland said.

The man told firefighters that he had the grenade from WWII and that he wanted to hand it over to authorities.  

The building was immediately evacuated and firefighters called in a state police bomb squad.
