You arrived at the base and your colonel offered you a drink at the bar. They told you that it would be better to agree because this is a great honor. And here you are sitting in the evening in some club, in a bar, chatting about something, but you went to the toilet, while you were there they added something to your cocktail, Koenig noticed this and took it to pour it out.

You didn’t understand why he needed your cocktail because he has his own, and he doesn’t like ones like yours.
