Facebook user Pennapa Castro uploaded the video from a Starbucks in Queens, N.Y. Castro said the incident occurred on May 12, where an employee allegedly went on a rant against a customer. That employee can be heard saying "you're not going to be served here. Bye. Bye. Bye."

The video quickly went viral, receiving over 1.5 million views since being posted on Thursday.

"I felt so bad for what happened, especially [sic] nobody I can report her to [sic] because she is the manager," Ruby Chen, the customer seen in the video, wrote on YouTube. I am glad that other customers in store saw how I was treated and told her "you need get fired." Then she switched the target and started to argue with them. I thank for this customer who took this video and sent to me."

"This is such a terrible experience," Chen said.
