A Starbucks executive was forced to resign Monday after she tweeted an offensive joke about blood.

“I had the worst night of my life,” Erica S. Pizzi, Starbucks vice president of global public policy, said in a statement.

“My blood was a little bit thicker than usual.”

Pizzis remarks came as she spoke at a Starbucks coffee shop in Atlanta on Monday, where she spoke about the company’s efforts to combat the use of blood in coffee.

“It’s not OK,” she said, according to an audio recording posted to Twitter.

“And we need to be aware that when we do use blood in our beverages, it’s not safe.”

Pizza Hut CEO Kevin Smith was similarly vocal in his criticism of blood, saying in a series of tweets that Starbucks “sucks.”

“Blood is a dangerous, toxic substance, and you should never drink blood.

Blood is an unproven, potentially harmful, potentially lethal, dangerous substance that needs to be stopped,” Smith tweeted.

The tweets came after Starbucks issued a statement in which CEO Howard Schultz said he had spoken with Starbucks co-founder Howard Schultz about his comments and that he had made a number of changes to the company.

“The statement I issued today was intended to clarify that I never said that blood was dangerous and that it should not be used in our coffee, and that I apologize for the impact my comments may have had on our community,” Schultz said.

Starbucks has been criticized by some coffee drinkers for the use and distribution of blood-based drinks.

In 2013, a New York Times investigation found that Starbucks had made blood-laced beverages available to customers in its stores.

The investigation was conducted by The Trace, a nonprofit that provides data to help journalists and the public understand the role of politics and economics in shaping public health issues.

In January, Starbucks announced that it was working to stop the use, distribution and sale of blood products in the company store.

“Blood products are an integral part of our blood and bone marrow products, including our blood-related drinks, blood and urine products, and blood products,” Schultz wrote in the statement.

In the statement, Schultz also announced that Starbucks would provide free blood testing kits to its customers who use blood-sugar-lowering drugs.

Schultz did not directly address the tweet, which has been deleted from his Twitter account.

Starbucks declined to comment to Newsweek on Monday.

The company is expected to make an announcement about Pizzes resignation on Tuesday.
