Starbucks Manager Verbally Attacks Customer After Thinking She Stole a Cookie Straw

A Starbucks employee has been fired after a video of her ranting at customers at a New York City store went viral online, according to sources.

Customer Ruby Chen, the main target of the employee's tirade, complained about the interaction on Starbucks' Facebook page and posted the video, provided to her by another customer in the store who filmed the entire incident on Tuesday.

Although the details are unclear, Chen believes her not being able to hear the baristas may have been the offense that set the manager off.

As she was trying to open her app, the location manager, who is only referred to as Melissa, started to go off at her.

The manager talked to her with a "bad attitude" and also started to yell. "The only thing I said to her is '[sorry] I don't hear you but you don't have to yell.' And till now, I haven't figured out which word aggravated her," Chen wrote on YouTube.

Melissa yanked away the app scanner when Chen tried to pay, and then "told me to leave and never go back" to the store, Chen said.

The worker then accused her of trying to steal the cookie straw she was holding.

"You're talking to the manager," the worker told Chen when asked who the manager was. "You're not going to be served here. Bye. Bye. Bye."

"Do you not get it?" the worker continued when Chen remained.

The worker was a shift supervisor, not a manager, according to a spokeswoman for Starbucks.

When other customers in the store began to speak in Chen's defense, the supervisor began yelling at them.

Chen said she was offered a $100 gift card and assured that the company was taking her complaint seriously.
