I believe that the reference refers to the day after Thanksgiving and has been around for years.
Police Search For Missing Oil Truck - Company Offers Reward For Information
EPPING, N.H. -- Police are looking for a missing oil delivery truck.Investigators believe the bright yellow Buxton Oil truck, carrying 3,000 gallons of home heating oil, was taken sometime on Friday.
Buxton said the company is offering a $3,000 to $5,000 reward for anyone who has information that leads to the arrest and conviction of a suspect.
The company said the truck and the oil inside it are worth about $115,000. The truck has the license plate AE7537 and the number 32 on it. It takes about nine months to order a new truck.
Buxton said she also is worried the tanker might be used for terrorism. Buxton said she and other fuel oil dealers received a letter from the government after the Sept. 11, 2001, attacks warning that terrorists were looking to steal fuel trucks.
Yup. Known as black friday in both retailing and advertising venues. For most papers, like the one I work at, it's the largest paper of the year.
