Starbucks is facing a $5 million lawsuit from a woman who claims their drinks contain too much ice.

Stacy Pincus filed the federal lawsuit in Illinois last week, claiming customers are being routinely overcharged and underserved.

"A Starbucks customer who orders a Venti cold drink receives only 14 fluid ounces of that drink – just over half the advertised amount, and just over half the amount for which they are paying," the complaint stated.

Pincus' lawsuit was filed on behalf of anyone who bought a cold Starbucks drink in the last decade. Her lawyer believes the damages could be much higher if the case is successful. 

Starbucks said the legal action is "absurd," advising unhappy customers to simply ask their barista for the cold drink to be remade.
