The ever-changing price of gas
As I was driving on the Indianapolis highway after visiting a customer, I saw a big electronic sign for a gas station and saw the price change as I was looking at the sign. While I first thought that it was odd for the price of gas to change in the middle of the day, I soon realized that the price was changing back and forth between the price that you would pay with a credit card and a lower price if you paid cash. The difference was 4 or 5 cents a gallon if I remember correctly.
I guess it makes sense since credit card companies take a percentage of any sale charged to the card, but it still looks very strange at first and I don’t think I had even seen something like that before the prices went so high. Maybe they’ll start offering specials if we bring big barrels every time and buy in bulk 
Only time will tell.
