Governments have to rely on compliance by people sticking to the guidelines. Whilst nobody wants to endure restrictions, particularly at Christmas, it is the only way that we are ever going to reduce transmission of Covid virus and bring the number of cases down.
This article from Sky News highlights the problem.
Police in Tier 2 York say they have seen huge numbers of people travelling to the city's pubs from neighbouring Tier 3 locations, in a clear breach of the guidelines.
In a statement aimed at people "flouting the regulations", North Yorkshire Police said they had handed out more than 160 tickets over the weekend after making visits to licensed premises.
Superintendent Mike Walker said: "Where we encounter people who refuse to adhere to the regulations and believe their pint is more important than someone's life, we will use our enforcement powers.
"Some people who were spoken to by officers did go home. However, our teams encountered large numbers of people who were not responsive to the advice, leaving us no option but to enforce through the use of fixed penalty notices."
Mr Walker added: "If you choose to visit the city of York from Tier 3 areas without a justifiable reason to have made your journey, with our extra patrols, chances are you will encounter one of our officers and you'll be asked about the reason for your visit."
