Once saw 2 fireman firing bird scaring flares, proceed to set fire to the grass area. Then they couldn`t beat the flames out with the floormats of their van. Next, they were unable to start the van to retreat from the fire.They then had to deploy a proper appliance to deal with the, by now, potentially serious fire.
I also saw a catering truck going way too fast on the apron take avoiding action against his colleague coming the other way....catering truck ended up shiny side down.
