SEASON 1, EPISODE 107 | AIRED ON 06/19/13
Floyd and Hattie's business suffers after Vivian puts up a billboard slamming the Love Train Diner for being closed by the Board of Health. Hattie gets her revenge, though, by spray-painting vulgarities on Vivian's billboard.
When Vivian confronts Hattie about destroying her property, an argument ensues, and the entire restaurant overhears Hattie warn Vivian to be careful that her restaurant doesn't burn down.
Unfortunately for Hattie, a suspicious fire erupts at Vivian's Diner, and it burns to the ground on that same night. After being accused by everyone—including her own family—Hattie is vindicated when the fire marshal determines that it was not arson but negligence on Vivian's part that caused the blaze.
