Wendy won't help others it seems
When she said she won't give her trade secrets to the business, because no one helped her...
I thought how selfish.
Does she honestly think some underling will usurp her? I don't think so, because there is room for everyone.
Plus, if she was smart, she should hedge her bets and help others. I'm not saying bend over backwards, but she should do a little more for women and minorities, who are trying to break into a mostly white male business.
If she hedges her bets, maybe that person will rise up in the ranks, and she might need a favor. They might be able to throw her a bone, or they can help each other.
