It seems to have been more like a typical Saturday night than a drunken New Year's Eve.

The reopening of pubs in England does not seem to have overwhelmed emergency services as many had feared ahead of the biggest easing of Britain's lockdown. But one senior police officer said Sunday it was "crystal clear" that drunk people struggled, or ignored, social distancing rules.

For the most part, people appeared to abide by the rules and rejoiced at the chance Saturday to lift a pint in the company of their mates, but in some places large crowds raised concerns that the deadliest outbreak in Europe may find fresh legs.

Chris Newell, a 33-year-old courier, traveled to trendy Shoreditch in east London to see friends.

"As long as everyone's keeping their distance, we're going to have a few drinks and just enjoy it and try and get back to a bit of normality," he said.

Health Secretary Matt Hancock said the vast majority of people did "the right thing" and abided by social distancing rules to stay at least one meter (over 3 feet) apart from members of another household and use hand sanitizers.

"It was really good to see people out and about and largely, very largely social distancing," he said on Sky News.

John Apter, chair of the Police Federation, who was on patrol in the southern England city of Southampton, said it was a "busy" shift, one that saw officers having to deal with naked men, "happy" drunks as well as "angry" drunks.

He said the shift "managed to cope" but it was "crystal clear" that those who have imbibed one too many cannot, or won't, socially distance.

Pubs and restaurants worked hard to get ready for the moment, spacing tables, putting some staff behind plastic counters and registering customers upon arrival. The wearing of masks is optional though, even for staff.

Rafal Liszewski, a store manager in the central London district of Soho, voiced concerns about the swelling crowds on Saturday.

"Quickly everything got out of control and by 8-9 p.m. it was a proper street party with people dancing and drinking," he said. "Barely anyone was wearing masks and nobody respected social distancing .... to be honest with that many people on one street it was physically impossible."

Some fear the British government is being overly hasty, even reckless, in sanctioning the changes. The U.K.'s confirmed virus death toll of 44,198 is the third-highest in the world, behind the United States and Brazil.

Critics note that the reopening of bars and restaurants in the United States and South Korea has been blamed for a spike in new infections

The four nations of the U.K. - England, Scotland, Wales and Northern Ireland - are moving at different speeds out of the coronavirus lockdown. The restrictions in England, with a population of around 56 million, or 85% or the U.K.'s, have been lifted the most, triggering concerns that Conservative Prime Minister Boris Johnson is being unduly influenced by a desire to kickstart Britain's ailing economy.

Johnson's office at 10. Downing Street, among many other places across the U.K., was lit up blue overnight to celebrate the 72nd anniversary of the formation of the country's beloved National Health Service, which gives free health care to residents.

A number of events are planned Sunday to celebrate its birthday. People are being encouraged to clap at 5 p.m. to say "Thank you" to the hundreds of thousands of NHS staff who have worked selflessly throughout the coronavirus pandemic.

After coming down with coronavirus himself, Johnson credited NHS workers with saving his life.
