Don't leave home without it

You know what VISA taught us about never leaving home without a credit card? I learned that lesson too well, but it's stupid, because nobody forgets their credit cards. They either had their wallets with them or not. People these days only forget CASH. CASH, CASH, CASH is used for so much. Donations. Restaurants. Chipping in for stuff. What is the correct amount of cash to carry around? My friend J.P. (name deleted to protect him from muggers) says $50 should be enough for day-to-day existence. I guess that means to carry it in various denominations.
