Want a Lawsuit With That? McD's Clerk Spits on Customer Customer claims rude treatment in the drive-thru lane By Nick McMaster, Newser Staff Posted Dec 10, 2010 5:06 PM CST 4 comments Comments An employee hands a drive-thru order to a McDonald's customer at the Rock & Roll McDonalds in Chicago, Oct. 15, 2007. (AP Photo/M. Spencer Green) (Newser) – It's a week for fast-food themed attacks—this one from the other side of the drive-thru lane. Would-be diner Sarah Thienes took a taxi to the window of a Chicago McDonald's and says she was angrily rebuffed when she ordered a cheeseburger—it was about 4am and breakfast-menu time, after all. She tried to adjust her order, was yelled at again, and when she finally got her bacon bagel sandwich, she says the employee screamed and spit on her. She is suing McDonald's for unspecified damages, the Chicago Tribune reports.
