my take on paper and metal for quenching your thirst for commodities
I rarely carry around money , as I believe that money-transfer with paper and metal is way too complicated to be taken seriously. There are all these kinds of problems with exchanging currencies, paying, receiving change (having ready the correct amount of coins), getting your hard earned {insert currency here, i.e. dollars, euros} from your trusted bank to your pocket burns fuel and time, carrying around vast amounts of paper or metal only for the purpose of exchanging CASH for GOODS.
