It's really true what people say about English politeness: it's everywhere．When squeezing past someone in a narrow aisle, people say "sorry"．When getting off a bus, English passengers say "thank you" rather than the driver．In Germany, people would never dream of doing these things．
After all, squeezing past others sometimes can't be avoided．and the bus driver is merely doing his job．I used lo think the same way, without questioning it, until I started traveling to the British Isles and came to appreciate some more polite ways of communicating with people．
People thank each other everywhere in England, all the time．When people buy something in a shop, customer and retail assistant in most cases thank each other twice or more．In Germany, it would be exceptional to hear more than one thank you in such a conversation．British students thank their lecturers when leaving the room．English employers thank their employees for doing their jobs as opposed to Germans, who would normally think that paying their workers money is already enough．
Another thing I observed during my stay was that English people rarely criticize others．Even when I was working and mistakes were pointed out to me．my employers stressed several times but none of their explanations were intended as criticism．It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable．This also is shown in other ways．British men still open doors for women, and British men are more likely to treat women to a meal than German men．However, 1 do need to point out here
that this applies to English men a bit more than it would to Scottish men' Yes, the latter are a bit tightfisted．
