Throwing a beverage cup harms the league's image more than attacking a bus with bricks.

At least the CBA thinks so as it fined the Beijing Ducks 110,000 yuan ($17,406) on Friday for its home crowd's uncivilized behavior during their opening finals game against the Guangdong Southern Tigers at the MasterCard Center (formerly Wukesong Arena) on Wednesday.

The fine almost doubled the amount the Shanxi Brave Dragons copped last Tuesday for their fans' unruly behavior, which included throwing litter onto the court in the semi series against Beijing and trapping the guest team's bus after a home game.
