Weird stuff happens a lot in San Francisco, and then theres this: a giant, orange Amazon locker thats appeared without warning, or explanation. Amid the throngs of tourists, Amazons put what it calls Giant, an aptly-named variant of its locker system that can be found in 7-11 convenience stores, and other retailers. Nor does it appear on Amazons list of available lockers in the city. Amazon did not immediately respond to a request for comment on the Giant locker, though The Wall Street Journal says its part of an event that Amazon plans to hold tomorrow, presumably to discuss whether this is just the start of a larger plan to roll out the massively-sized outdoor lockers in other cities. Amazon currently has eight lockers strewn about downtown San Francisco, with most of those located in the Northeast part of the city.
