I'm from the UK but just returned from living in Paris. It seems to me that both cultures are polite in different ways. Some examples,
In France, people are more likely to use social titles. "Monsieur", "Madame" etc. are used when talking to strangers, whereas British English speakers seem to avoid using titles, even over the phone with, for example, the bank who will sometimes (which I find a bit rude) address you by your first name.
Similarly, whenever I walked into a shop in France, I would nod and greet the shopkeeper, but that seems not to be so widely practiced in England.
On the other hand, English people apologise when you bump into them (a well known stereotype I think). If you accidently walk into an English person, it's usually they who apologise, whereas as the French will expect an apology from the person doing the walking-into.
In France, when getting onto a lift, everyone greets each other, and when each person dismounts they will all wish each other a good day. This is something I miss in England. I find English people to be a bit more reserved in that aspect. I even walked into my doctor's waiting room in France and was wished a 'bonjour' by the other patients.
One other thing I like about French politeness is that when you arrive at a party, even among people of my age group (early 20s), the host will introduce you to everyone, whereas in my experience in England you arrive at a party and go and talk to people you know but no-one introduces you to the strangers there.
But, the big thing I missed in France was queueing etiquette! The French never make a single line for multiple cashiers as is the English habit. When you shop, there will be several, each moving at a different pace. French people will sneakily switch queues if they can benefit, or even stand between two queues until they see which one is moving faster. Such a headache for an Englishman!
