A furious mother who was shouting at protesters during Just Stop Oil's "slow march" demonstration in central London was told to think about the plight of dolphins by a passer-by.The unnamed woman confronted the activists and told them her son was "missing out" because their actions were stopping him from getting to school."You're parents! Come on guys. Move and let the bus go! We got kids on the bus. F**** sake," she said.However, a passer-by appeared to side with the protesters, telling the woman to think about "all the dolphins that are dying".
