I hate to be that person , but things like this are he exact reason you need to be prepared . I always bring an extra change of clothes , never have my phone in my apron , always be prepared to stay late on busy nights . It ' s part of working in the industry . That being said , a manager should never promise when to cut someone . My staff knows to not even ask me to be cut at a certain time , unless it ' s an emergency and they want to be first cut instead of last and the other staff is cool with it , because I can ' t tell you how busy it will be at 7 . <| sep |> I had a similar problem , no space and not that much cache used by apps . The big app download trick was not freeing that much space , so i started deleting apps and as soon as i deleted instapaper and flipboardwhich were both reporting normal sizes i went to check and suddenly had like 4 gb free . The other space is about 700 mb now .
