When my dad bought his 67 Barracuda 383 Formula S 4 speed, he pulled out of the dealer's lot and ran out of gas... The dealer refused to give him a gallon so he could make it to a gas station to fill up, so he ended up arguing with the owner's son on the showroom for a half hour and after watching some customers walk out when they figured out what was happening, dad left and walked to the gas station and bought some gas in a can to get him to the station to fill up...
He never went back to that dealer...
They eventually went out of business...
