Wealthy men do not carry wallets full of cash. Cash is for manual laborers and/or "those people" who use payday loan services.
some of us enjoy redundancies. nothing wrong with having a few hundred on hand. if the power is out, if SHTF, cash is always king. I don't always want to hand my card to some shady looking cashiers or waitresses, splitting big tabs can be risky. I try to always have a few hundred in 20s as well as 10, 5, and 1s. Ya never know.
