Nothing beats a 1980s brick phone
In the late 1980s, a story entered advertising folklore. A group from an ad agency had boarded an evening train from Newcastle to travel home from a client meeting. On boarding, they learned that the buffet was out of action, and they were hungry. Happily, one of them was carrying in his briefcase a wondrous new brick-sized device called a mobile phone. After a series of rebuffed calls, he managed to find a lone Indian restaurant in Peterborough willing to deliver to their train when it stopped en route to London; there our hero duly handed a wedge of cash through the carriage window before taking delivery of the food.
