January 15, 2010 -- A floor collapsed beneath a group of about 20 members of Weight Watchers as they gathered to compare how many pounds they had shed over Christmas. Members of the weight-loss club were lining up to compare readings on the scales when they heard a bang as the floor came away from the walls of their meeting room in Växjö in southern Sweden. “We suddenly heard a huge thud – we almost thought it was an earthquake and everything flew up in the air. The floor collapsed in one corner of the room and along the walls,” one of the those present told the Smålandsposten newspaper. They abandoned the room as the floor started to give way in other areas. "We are going to have to find a replacement premises," Therese Levin, a consultant for Weight Watchers told the newspaper. No one was injured in the incident, the cause of which is being investigated. The scales were not damaged and the weigh-in continued in a nearby corridor.
