Shae had been in the hand's tower before. She had seen Tyrion wear the chain before when he was serving as hand. She knew Tywin was the hand presently as she testified in court with him as a judge.
What whore would don his chain, have sex with someone in his bed, and just linger there unless she felt comfortable? But we can also just turn to the text for the proof. I'm just going to quote what she says directly and summarize the action. My kindle says this starts on page 877 (total pages = 973).
"M'lord?" a woman's voice called.
Tyrion pulls back the drapes and sees her turning towards him with "a sleepy smile on her lips" which "died when she saw him." He asks if she was expecting someone bigger. She leans up, revealing she's wearing the hand's chain of office and:
Big wet tears filled her eyes. "I never meant those things I said, the queen made me. Please. Your father frightens me so."
Tyrion shares that he had spent all his time in the dungeons dreaming of her, in silk, rags, or nothing at all. She then replies
"M'lord will be back soon. You should go, or... did you come to take me away?"
Seems to me she knew exactly where she was and who she was pleasing.
I had completely forgotten that Varys mentioned that a previous hand use Chataya's tunnel, as he was to proud to reveal his indulgence publicly. So if having sex with a whore seems out of character for Tywin it's because he took caution to hide his activity. Little surprise he resents his dwarf son for publicly bragging about his whores. Tywin probably wanted to show Shae the real "giant of lannister," forcing the woman his son used to openly to defy him to submit to him sexually.
And I honestly just think GRRM had Tywin on the privy so that he could add the line about the jape at the end of the chapter. All the events involving the crossbow and Tywin led up to that as a buh-dum-cha punch line.
And to address the smell of his corpse, I just thought it was fitting because he was a rotten man inside. It's a minimalistic interpretation of his smell, I admit. However, the Red Wedding proved that Tywin was willing to permit
the unthinkable as long as it didn't sully House Lannister. I will give him the benefit of the doubt in regards to not knowing how brutal Ser Gregor was, but the Red Wedding is proof enough of how wicked this man could be. Shall we also cue Rains of Castamere?
I just see these "TYWIN DOESN'T LIE WITH WHORES!!" argument a lot and I don't really see the grounds. Tywin was only concerned about keeping the Lannister name clean and lawful in appearance. In D&D talk this is called Lawful Evil. He acts within the bounds of the law (as far as appearances are concerned) and administers it to anyone that dares to defy him. He rose the House back into greatness and wanted it to stay that way for centuries after he was gone.
Don't confuse the book with the tv show character. Which, I must say, I am a fan of TV Tywin.
