After handling the formalities of the press conference, it was already past three in the afternoon. Although it had been a busy day, completing everything at such speed was something unimaginable, if not unprecedented.
Normally, if a company wants to hold a press conference, every department drags its feet. Without some benefits and the right attitude, there's no way to get things done smoothly.
To give a down-to-earth example, when ordinary people want to get some kind of certificate, they often have to watch the clerk's mood; if you're a minute early or make them stay a minute late, they couldn't care less. If there's anything missing in your preparation, they'll either tell you if they're in a good mood, or they'll leave you to figure it out on your own if they're not.
