Good friend of mine, excellent income, plenty money in the bank, owns a beautiful, spacious custom built new home on over 300 acres, always uses credit, debit and online electronic bank withdrawal to pay for everything. He rarely ever carries any cash on him at all -- not even pocket change.

During the widespread power outage caused by the big ice storm several years ago he was driving back home after attending a annual sales meeting in Nashville.

He said about half way home he got thirsty as heck and wanted something to drink. Even though it was still fairly early nothing was open due the power outage but he eventually did find one outside soda pop machine that still was working -- problem was, he didn't have any real money on him to even buy a soda.

He said he searched all through the inside of his truck and finally scrapped up just enough loose change to buy a bottle of soda pop.

Luckily he had enough fuel in his truck to make it back home.
