So... you spent $2.25 for a Coke?"EDGE" is hard work and bit of luck.
Tonight I used a $5 bill to get a coke out of a vending machine, got change of 2 one dollar coins and 3 quarters. Since being a kid, always looked at coins, hundreds of times ordinary coins, tonite was 1979 Susan B Anthony with San Francisco mint mark, worth more than a buck.
So knowledge and personverance come together.
