Serving through a wall opening is a recurring solution to the same problem: how to sell something small and hot to people who are walking. Florence's wine windows, cut into the walls of palazzi in the 1500s, are the famous ancestor; they were revived in the 17th century as a plague-era hygiene measure and restored again in the 2020s. Naples built an equivalent culture around coffee served fast at street level.
The specialty-coffee era miniaturised the idea. Kiosks, hatch windows, and literal holes in walls appeared in cities from Melbourne to Tokyo, and short-video platforms finished the job: a window is a perfect frame for a vertical video. The Seville example documented on this site is one entry in that longer, international list.
