Starbucks has admitted that it accidentally overcharged a million customers at more than 7,000 stores over the Memorial Day Weekend when, at the end of the day, the company's automated system charged people's credit cards a second time. This is not to be confused with the deliberate overcharging the company does every day by selling lattes that cost 12 times the price of a barrel of oil.
