Social customs
When you go to Germany you will probably want to adapt yourself, in reason, to German customs and conventions. You will find, for instance, that most German men wear hats which they doff with a sweep whenever they meet anyone they know, both male and female. … Even if you wear a hat, however, there is no need to become flamboyant in acknowledging or giving salutes …
Ladies should not smoke in the street, although they can do so in restaurants and, without offence, in smoking compartments on trains. There are no special restrictions on women’s dress, such as the wearing of slacks.
As the Germans do not show the same self-discipline which Britons possess, you will find that there is no queueing, say for buses, and it is often a case of the most pushing persons being first. Nor do the Germans have our particular sense of humour – theirs is rather a “heavy” brand – so, however well a German may speak English, he will seldom be able to understand (or appreciate) what I might term “sly digs.” It is best to be careful in this respect.
You should learn how to schunkeln, which is a swaying of the body to keep time with music or singing, usually linking arms with those next to you – even if you do not know them. This sociable action occurs quite frequently in places where people are in a merry mood, so there is no reason why you should be the odd person out.
