Two people were injured Wednesday when a fire engine slammed into a North Texas Dairy Queen. City officials said Greenville Fire-Rescue Unit 4 crashed into the restaurant located on the 200 block of Highway 380 East in Farmersville at about noon. The truck was headed east on U.S. 380 when it left the road for an unknown reason."It happened right in front of me," said restaurant manager Babbett Pattillo. "I mean, I was on the phone looking out of the highway and taking an order when it came right beside me. It just took out everything."
