When you offer a draw and your opponent runs out of time without accepting it it is considered draw by 'mutual agreement.' But the opponent needs to accept that offer, and they didn't. So they simply ran out of time and because of the offer it was automatically considered a draw. This happened to a friend of mine and I found it unfair. Here is the game I am talking about, my friend was white.
On move three, black was obviously stalling, and so white offered a draw. Now black didn't accept it, but continued to let their own clock run out and waste time. So they should lose the game. But since the draw was offered, even when black ran out of time it resulted in a draw.
