Running The Clock Down. Fair?

Just played Creative Control and tho' I held a slight advantage the game with 15 minutes left ran into a bit of a stalemate. I offered a draw but because his advantage was 2 minutes on the clock he refused the offer. Continued to just move his Rook backward and forward running the clock down. I was obviously now holding a losing hand and subsequently lost a game that from an ability point of view I was the better player. Fair or just tough luck on my part? By the way his response at the end of the game was LOL.
