Has anyone else met a player like this? There was no pawn left, yet my opponent had to reach the limit before he agrees that yes it is a draw. In my opinion, albeit not against the rules, it was very unsportsmanlike. In the game, I blundered my rook after about 40 moves and resigned, but that was entirely on my part.
Should this trouble me, or, instead, should I also do the same in my future games, since 'a game isn't drawn until you agree to it'?
