A Utah food delivery customer said he ordered a milkshake through a food delivery app but instead got a cup filled with urine. Caleb Wood, of Saratoga Springs, said he ordered fries and a milkshake from Chick-fil-A through the Grubhub app earlier this week. “When I started eating my meal upon delivery, I put a straw in my cup that was delivered and took a sip,” he said. “I soon discovered that the cup delivered to me from the Grubhub driver was a warm cup of urine.”. Talk about being P O'd!
