The idea is quite nice, turn the vending machine into a slender pole, reminding people that Diet Coke is the skinny choice. The 1 minute and 44 seconds showing it off is a bit much though, the idea is easily understood it from the first shot.
The machines were spotted all over Paris, giving away free diet coke. At hairdressers, in gyms, squeezed between other vending machines, in the middle of the bridges, streets and cafés. There's even a pinterest shot in this study, no idea why anyone would be pinteresting that they spotted this machine.
