Out of interest, why would you ask MN this and not look at the official government site where the advice is actually published? I can't understand the logic.
Since when has "official government advice" been a paragon of truth? The "official" line is often very different from what actually happens. By asking on social media, people can get more of an idea of what
really goes on.
The government is always talking about fines for this and that, with little or no intention of enforcing them; as others have said, the government have cut their own resources (i.e. the police) to do so. Instead, they concentrate on things which are easy and cheap to enforce, such as parking. They always have done, always will; even before the pandemic.
Remember also Sir Humphrey Appleby's observation in Yes Minister: "It's the law of inverse relevance: the less you intend to do about something, the more you have to keep talking about it." So they talk about fines, to scare the public, with little or no intention of actually applying them; just throwing in a few token ones to appear as if they're doing something, and to get a few headlines. It's performance politics, Saint Boris's (only) excellent quality.
They might use their facial recognition CCTV to try to enforce this, but people have their faces covered, on Boris's order: oops.
