Opening times vary a lot, mostly depending on demand.

the health service  part... it doesnt explain how we pay our national insurance contributions...   the more hours you work the more national insurance you pay... so a person doing 40 hours week would pay more than someone doing 20 hours a week but they both get the same health service...

I left with my friends at 3 or 4 a.m. I think. The barkeeper has allready gone. he knew us.

The narrator is partly wrong about parks. A high % of them close at night. Some of the benches in them - & elsewhere - are designed to be uncomfortable to deter people laying on them or even sitting on them for long. The Camden Bench in London is an example of that.

the UK doesnt allow you to cross all roads...  like the motorway you cant walk across that...  or slip roads.

No we go crazy at 18 or 16. Really we are no better, but at 21 we will have developed a pretty good sense of how much alcohol you can take. We all had our blurry nights and hangover mornings, you only learn where your limit is by crossing it at least once. Also, as long as you can lay on the floor without holding on to something, you are not drunk.

England united kingdom 🇬🇧

eggs...  wrong we do refridgerate them, they are usually found in with the bottles of milk...
parks... wrong again there are hundreds of parks that close after 5 pm

Rule Number 1: don't listen to an American trying to explain Laws and Culture about the UK.

Firstly 3an is a lie it's 24 hours. It's up to the bar or pub what time they shut.
Depending on the location.

You don't need Smart cards you just need Apple/Google Pay. It works the same.

Only in England you pay for a subscription, again and American,  not knowing there are 4 different countries in the UK and in Scotland the University is Free.

Im get frustrated with American talking about the UK as if its England. England doesn't have laws or rules. They are UK rules and laws and the UK is 4 countries. Scotland, England, Northern Ireland and Wales
