Well,you see the thing is most people who live in the UK fully support the Immigration service in trying to keep out unwanted people.
It sometimes,but not always,prevents bombs going off in our capital and killing our citizens of which there have been quite a few.
And if that means some travellers are inconvenienced by immigration officials doing their job then who gives a monkeys.
If you have a genuine reason for travel,evidence to prove where your going and funds to cover your stay in the UK so you're not sponging off our taxpayers like an awful lot of foreigners already are then the Immigration service will treat you like they do in America and anywhere else.
There is no such thing as an easy entry into a country,anywhere.
It's a fact of life.
