As the price of fuel had dropped three times in a row, and a holiday weekend was approaching, I figured we were due for an increase, so I topped the tank off. I squeezed as many drops in there as I could get, which is not really good on your engine, but I wanted to brag about those extra cents I saved. Then I went on about my errands.
When I went back through town 20 minutes later, the price had gone down almost 10 cents.
I just had to bitch about that to somebody.
