However,from what I have seen of the Polish in the UK they are definitely more 'old fashioned' and have better manners than modern British people- I think this is due to Poland being a more traditional,disciplined and less wealthy nation.
I am a UK citizen and have been living in Poland for the last 3 years. I like the Poles, but i find them to be very reserved in their behavoir. They are generally not the kind of people who 'like to let there hair down', and are definate'ly not 'go with the flow' types. Many Poles, more so among the older ranks, seem obsessed with there own behavoir, striving hard to be decent and civil at all times. These types often attempt to inhibit others from behaving free'ly.
Polish people are very judgemental, if you clank your spoon against your cup when stirring your tea, or tip your bowl towards you rather than away from you when finishing your soup, expect to see eyebrows being raised. If you do not wish to be considered as a modern day caveman, then dont stand with your hands in your pockets or talk too loud when your in a shop.
Polish culture is steeped in tradition, its almost impossible for a 1st time visitor not to make a thousand blunders within his first week, but do not fear, the Poles will have you corrected and up to speed on exactly how you should be behving in no time! They are very good that way!
As you may have figured by now, i much prefer the uninhibited freedom of the British culture! Poland needs to let its hair down!
