25% of gas stations in NY overcharge.

From the Consumerist:

New York's Attorney General, Andrew Cuomo, is warning consumers after an undercover investigation found that 25% of gas stations are engaging in "deceptive practices, including wrongfully surcharging credit card customers." The AG says that under New York state law, retailers are not allowed to impose surcharges for using a credit card.

The AG also said that the stations were engaging in false advertising by only listing the lower cash prices on signs, leading to nasty surprises for consumers once they parked at the pump.
