Sgt. Aaron Dunbar says the robber entered Elmer's Restaurant late Monday wearing a green hooded sweatshirt, gloves and a beanie atop a shoulder-length blond wig that was pulled partly across his face.
A bartender tried to bat away the can of insect repellent when the robber brandished it, but the employee got a direct spray to the face.
The Roseburg News-Review reports the robber grabbed money from a cash box behind the bar and fled. The amount of the take wasn't disclosed.
