A Las Vegas McDonald’s worker was arrested after a customer complained that they ingested spit when drinking an iced coffee and then became infected with COVID-19.

Police issued a warrant for Felicia O’Neal’s arrest for the December 2020 incident and picked her up on an unrelated traffic stop, KLAS, a CBS affiliate out of Las Vegas, reported.

In her complaint, the customer said that she had ordered French fries, a milkshake, and an iced coffee at a Las Vegas drive-thru, when “the employee became rude and [the customer] asked to talk to her supervisor,” according to the police warrant obtained by KLAS.

The warrant went on to say that “[The customer] said that she received her fries and shake right away, but the iced coffee took a bit longer, which she thought was unusual. After a bit, [the customer] said a black female, who could have been the person she initially had the problem with, brought her iced coffee.”

When the customer’s ice coffee was ready, the customer said O’Neal handed her the drink and slammed the window of the drive-thru shut, according to police.

When the customer arrived home, she saw mucus in her ice coffee at the bottom of the drink, only after she “sucked up the mucus with the straw,” causing her to vomit, KLAS said.

After the incident, the customer called the McDonald’s manager, who told her “she was too busy to check the cameras at that time,” adding that an employee would not be “stupid enough to do that with cameras everywhere.”

Several days later, the customer tested positive for COVID-19. Her children, aged 2 and 5, also caught the virus, the News & Observer reported.

”I felt violated! I felt absolutely violated and I had a concern about what you could potentially get from ingesting someone’s spit,” the customer told KTNV, an ABC affiliate out of Las Vegas, back in May 2021 – shortly after the incident occurred.

In the surveillance video, O’Neal was shown pulling down her mask and spitting in a cup before it was filled with what appeared to be coffee.

O’Neal, who is facing a felony charge of adulterating food, water, or medicine, was picked up for driving without headlights. Her warrant was issued in 2021.

The McDonald’s employee’s bail was set for $5,000, and she had bonded out of the Clark County Detention Center in Las Vegas as of Tuesday, KLAS reported.
