Someone been putting up fake power outlets at airports using stickers you can buy off of Amazon. Best I can figure it’s just meant as a cruel, cruel practical joke.
We all need to quickly charge devices between flights, especially when we’re flying planes and aircraft without seat power (and without seat back entertainment, where we’re forced to use those devices for entertainment). And airports are notorious for their lack of available outlets for passengers. Spotting an outlet may seem like the holy grail, but turn out to be a mirage.
