Opponent repeatedly offering draws early in the game?


Normally, people do this when they're sore losers and have just blundered their queen.
Even if that's not the case, there's no excuse to do a long game if you can't stay for a long time. I get that things sometimes pop up out of nowhere, but that's why you should be prepared. If you have even the slightest suspicion that something might happen, don't do a long time control.
