Adi thought that it was crazy to bring someone work while they were recovering from a gunshot, but when the bosses tell you to do something, you do it with a 'ya, Herr.' He knew Hans from work, but they weren't exactly the close. Adi also got the feeling that he would be questioned highly about this visit once he came back in to work tomorrow, so he wanted to make this visit short, for both of their sakes. He knocked on the door, trying to make himself heard over the music that he could hear coming from inside the place.
