WATCH: Racist woman booted out of Starbucks for ranting about Korean student speaking 'Oriental'

An unidentified woman was kicked out of a Starbucks in Walnut Creek, California, earlier this week after she angrily told two students who were sitting near her to stop speaking "Oriental."

Local news station KRON 4 reports that Korean exchange student Annie An was doing school work with her tutor, Sean Lee, in the Walnut Creek Starbucks when a woman sitting nearby told them to stop talking.

While they didn't understand what she wanted at first, they quickly realized that she was upset that they were speaking Korean to one another.

At one point in the dispute, Starbucks staff members came over to ask the woman what her problem was.

"They're speaking in Oriental," she replied. "I hate it."

When told by the Starbucks employee that the students were allowed to speak to one another in Korean, she replied that former President Barack Obama had once said that people who live in the United States should learn to speak English.

Sean Lee, who is fluent in English, told KRON 4 that he was shocked by the woman's outburst.

"Out of nowhere, we didn’t provoke her," Lee said. "We were just minding our own business. This lady just suddenly says, 'Don’t you dare say that again.'"

Starbucks employees asked the woman to leave, but she refused. They then called the police, who promptly removed her from the cafe.
