I'm not lovin' it.

Two women who were kicked out of the McDonald's on 69th Street in Upper Darby Wednesday afternoon for engaging in sexual relations in the bathroom were jumped by a group of customers once they exited the restaurant, according to police.

Shortly before 5 p.m. a group of customers went to the manager of the McDonald's and told her that there were two women engaging in sex in the restaurant's second-floor bathroom, said Upper Darby Police Superintendent Michael Chitwood.

"Everybody should do their own thing but doing it at 5 o'clock in the afternoon in a McDonald's bathroom - whether you're female and female, female and male or male and male - what the f---?"

The manager went to the bathroom and threw the women out of the restaurant, police said. Shortly thereafter, the group of seven or eight people who had complained about the women ran outside and began assaulting the couple, Chitwood said.

One of the women was stabbed in the shoulder with an unknown object by a female in the attacking group who appeared to be around 40 years old and had two children with her, police said.

As police arrived, the crowd scattered. Officers had to convince the stabbing victim to seek medical assistance at a hospital, where she was treated for her injuries and released. The couple said that their attackers used derogatory language against them during the beating.

Police are in the process of obtaining surveillance footage from the McDonald's to determine the identity of the attackers.
