Daniel turned around to leave, but Rachelle had wanted to buy the trench coat with the intention of spiting Cheyenne in the first place. If they left now, it would mean that they admitted defeat in front of Cheyenne.
So she would make Daniel buy the trench coat regardless of what it took! "Honey, this is such a nice trench coat, and it really suits you well. It's simply made for you. Just buy it!"
In Rachelle's opinion, the trench coat might be a little too long for Daniel. But no matter what, she wanted to one-up Cheyenne and outdo her. Although $90,000 wasn't a small sum of money, it wasn't like Daniel couldn't afford it, or so she thought. She felt that he had to buy it even if it was purely for the sake of her pride.
