A Profitable Gas Station
There are three sections that are present on a gas filling machine. These sections indicate the sort of gas that is available at the gas station along with the price. Accordingly, the order starts with regular at the very left, plus in the middle, and then the premium at the very right.
In the concerned gas station, the order has not been followed. Rather, the regular section has been placed in the middle whereas the plus section has been shifted to the right. The common practice of the people is that they mostly use the regular gas that is located all the way to the left.
