Staff at a branch of McDonalds were forced to barricade the door after ejecting a group of rowdy youngsters. It comes as the fast food chain announced it is banning all unaccompanied under-18s from their restaurant after 5pm due to a spate of attacks on staff. The kids at the Chatham branch in Kent appeared to jump on tables, spit and swear at staff and hurl signs around. They were even popping children's balloons. As a result of the rampage, workers at the eatery had to get the customers, who all appeared to be children, to leave on Sunday at around 4.30pm. The door to the McDonald's was closed behind them and the entrance was barricaded with a floor sign. A man who appeared to be a staff member forced two of the youngsters out the door, after two girls were seen in a video of the ruckus jumping on a table. A young girl was talking on her phone as the front door was closed off, claiming one of the group was called a "s**g" by an employee and were not allowed to leave. As staff barricaded the doors a young girl waked behind a female employee and kicked the sign, just inches from where the worker who put it in the doorway was standing. While the door was blocked, youngsters who were left inside the branch began arguing with staff until they were let out. Once outside, a girl could be seen appearing to spit in the face of male McDonald's worker as she stood by the entrance. The reeling man seemed visibly shocked by the incident and wheeled away from the scene to start making a phone call. The temporary ban on under-18s entering the restaurant after 5pm without an adult was recently brought into force at McDonald's in Lord Street, Liverpool. Restaurant bosses confirmed this move was due to a rise in staff being subjected to what was described as "verbal and physical abuse". A customer, who did not want to be named, filmed the chaos happening in Chatham - that was recently slated as the UK’s 'slobbiest place', with 64 per cent of people believing the town was “beyond rescuing”. Chatham residents recently fought back against attacks on its reputation as being the "home of the chavs".
