I'm a big fan of all things LearnVest, and I love this Sh*t Girls Say About Monday video.
I especially love the bit about the girls trying to pay a restaurant bill with a million different debit cards. Chicks never bring cash with them to restaurants, and I've never understood why. There is an ATM on literally every corner of New York City.
Also, trying to make the bill fair? Just split it equally among everyone. Who cares who had a Diet Coke versus who had a Chardonnay? You're their for the company and conversation, not to needle over the check.
