SIMPSONVILLE, S.C. (AP) -- Greenville County deputies say a McDonald's employee spit in the iced tea of two customers after they returned them saying the drinks weren't sweet enough.
Investigators say surveillance video caught 19-year-old Marvin Washington Jr. leaning over the cups before he filled them at the Simpsonville restaurant on Saturday.
Authorities say the customers discovered the phlegm when they removed the lids of the drinks to put more sugar in because the second glasses also weren't sweet enough.
Washington was arrested Wednesday and charged with malicious tampering with food. He could face up to 20 years in prison if found guilty. He is in the Greenville County jail awaiting a bond hearing, and it wasn't clear if he had a lawyer.
