An article in the Telegraph a couple of weeks ago was written by contributor who wanted to remain anonymous.
She had returned from abroad and the family were supposed to quarantine for two weeks, by about day 10, no symptoms and fed up so she visited the corner shop, then farther afield.
When in Waitrose, she received a call asking if she was at home, to which she replied saying yes. Then asked why she wasn’t answering her doorbell!
Result, £1000 fine, apparently if she had admitted it straightaway would have got off with a warning, but because she lied....
She was mortified, no doubt as a result of being caught out.
A random check maybe, but that’s what the article was about,
