It’s curious that we have two nearly identical stories of police doing undercover work to shutdown hairdressers in 2 different countries for not obeying the benevolent government lockdown rules.
Almost as if the stories were planted.
I think it`s underground as in down in the cellar, not undercover. I don`t think anybody “planted” anything. Probably the neighbours saw people with freshly cut hair leaving the houses and called the police.
