Yeah , the barista in this video fucked up by even accepting to make this ladies drink . That being said , there ' s a chance she wasn ' t shorted . Sometimes shots of espresso can be more or less liquid than you expect , they are fickle . I doubt she was shorted on anything . I ' m sorry that you have had bad experiences with some of your drinks . I ' m sure that your Starbucks would be more than happy to fix any of those drinks for you . <| sep |> This video from 2013 seems to be arguing the difference between being mauled to death by one lion and being mauled to death by 20 . The runaway effect is not needed to catastrophically affect life on the planet . it won ' t matter what happens after the temperature rises 6 degrees because most life will be dead . Downvote and move on .
