It was a while ago, but there is this notorious gas station in Sausalito, California that had this short period where the owner kept on just jacking up the prices for who knows what reason. Well - he was raising it higher and when the complaints started, they went up even more kind of as a sick joke. And since it was a tourist spot some people were still paying it. He was probably making more profit off the gas than ever since it's usually tight margins. But even locals who knew that the Shell station a mile away was less than half the price still went there out of "convenience". There are better photos of this place, but the only ones I can find of these prices were taken from screen shots of video and just blown up.
