A guy in London filmed one person after another slipping on the same patch of ice on the sidewalk across from his house.  The video shows 12 different falls, give or take.  He told the DailyMail that around 30 people fell in ten minutes.

He also said he tried calling the city to make a report, but couldn’t get through, so he filled up some trash bags and put them in front of the slippery area.
