gas pump measurement

Most of us likely assume that the gas pump that is providing petrol is giving you the fuel that you pay for – no more or less. While that may be true in most cases, ABC News in Baltimore, Maryland proves that sometimes pumps do bad things to good people.

The report details Maryland state gas station inspections that have revealed over 4,000 defective pumps over the last four years. In all, that's between five and six percent of the 40,000 gas pumps in Maryland, or way too many error-prone pumps for our tastes.

While our primary concern is that customers aren't getting what they pay for, it seems the gas station owners are more likely to get the short end of the stick. The report claims that station owners are three times more likely to lose money than the customer. Scroll down to watch the ABC News report.
