Being polite is very important.(1) If you are polite to others, they will be polite to you. 

In English there are many words to show your politeness; the use of “sir” and “madam” is not an important one. These words are used far more rarely than we think. In Britain, it is unusual for someone in the street to say “Excuse me, sir.(2) Can you tell me the way to the station?” The people who use the word “sir” in this way are usually expecting some money for a service—a taxi or a waiter. For example, “That will be $12,sir.Thank you!” 

The word “please” is used everywhere in Britain.(3) Many visitors don’t know when to use “please”. When they go into a cafe they say “A coffee.” or “I want a coffee.” or even “Can I have a coffee?”(That might be really alright in their own languages).However,(4) it seems that they are impolite! Just adding a simple “please” would make it better —“A coffee ,please.” or “I would like a coffee, please.” It is better and safer to always use “please”! 

Let’s look at polite ways of asking questions. Instead of a direct question we often use “Can you” and “Could you” before we say what we want .Look at these examples, which are from a normal conversation at home between husband and wife: “Can you park your car over there, please?” “Could you move the table against the wall, please?”

“Could...?” is a little more polite than “Can...?”,but both questions contain the word “please”.

If you are not a native English speaker ,then to use “Can...?” and “Could...?”to express a request is wise. In fact, you can be even more polite: “Sorry, could you tell me the way to Oxford Street, please?” “Sorry, could you tell me your name again, please?” (5) it’s, with, the, word, request, very, common, to, start, a, “sorry”. 

If you ask for help, try “I’m sorry to bother you, but could you help me, please?” You might say to a friend “Hey John, lend me $100,will you?” But you couldn’t say this to somebody you do not know well.
