This is true. The other week, I pulled into a parking lot across the street from a building at the same time a fire truck pulled up. I noticed all the strobes, alarms going off and people coming out but couldn't see anything. I figured it must be a false alarm. I walked around the other side and then I saw a garbage can on fire underneath the covered drive through area of the building. Just goes to show you it's always better to evacuate instead of speculate.
