It's pontless complaining about Polish immigration to Britain, unless the government does something to sort out unemployment amongst indigenous Britons, obviously people will come over from Poland to work. It's a mutually beneficial arrangement for both the Poles and companies in Britain,what's the point of having a go at the Poles themselves?? Britain has a long history of immigration and as a society will cope perfectly well with Polish immigrants, or any others.
The Poles who arrived in Britain after the war proably did integrate more quickly but there were fewer in number and many married British women. When I was growing up in Birmingham my Dad had a couple of Polish friends (who taught me and one of my sisters Polish), the guys were well settled in the local area but still proud of their heritage. My only gripe with Polish immigrants is that SOME BUT ONLY SOME would be nasty if we had Black or Asian workers in the factory where I used to work.
These were not educated people and all ethnicities are guilty of ignorance at times. Maybe some Poles could try harder with the language but then as Brits we aren't saints either! As for sklepi well why not? some of the food is nice.
Everyone has their own opinion on The EU/Commonwealth/immigrant workers but at the end of the day it's the government which is the problem ! If the jobs are here now or in the future well who cares which people take them?
As for integration it will come eventually and if Poles are returning to Poland well it won't really matter!
