Marvin Washington Jr., South Carolina McDonald's employee, arrested for spitting in customers' drink

(CBS/AP/WLTX) SIMPSONVILLE, S.C. - South Carolina county deputies say a McDonald's employee was arrested after he spit in two customers' cups of iced tea after the drinks were returned because they weren't sweet enough.

According to police, 19-year-old Marvin Washington Jr. was arrested Wednesday and charged with malicious tampering with food.

CBS affiliate WLTX reports on April 14, a mother and daughter ordered sweet tea from the drive-thru of the McDonalds.

The woman claimed it wasn't sweet, so they asked for new drinks. Authorities say the two then discovered a large deposit of phlegm when they removed the lids of the drink to add more sugar because the second round of beverages still weren't sweet enough.

The alleged victims then called law enforcement.

Greenville County investigators say surveillance video caught Washington leaning over the cups before he filled them Saturday at the restaurant.

The McDonald's owner says he follows strict food safety procedures and asks people not to reach conclusions until all of the facts come out.

Washington was booked at the Greenville County Detention Center. It wasn't immediately clear Wednesday if he had a lawyer.
