The Hangover Part II Plot holes

Minor Plot hole: Teddy's father, an asian man who saw his boy as his biggest achievement and pride of his life, is almost unfazed by the fact that his current cello-virtuoso and future surgeon kid lost one finger due to a drunk night in Thailand because of Stu and his friends.

Not only is he not threatening to call the cops for having drugged his underage kid, he also gets pressured by Stu into finally accepting him as a legitimate husband for his daughter.

Unadressed Issue: Teddy was the first one to wake up after the wolfpack's intense night. He subsequently got stuck in an elevator. Did he try to scream ? He was there for a full day, clearly someone would have heard him.
