Personally I find treating people exactly the same as they treat you to be a good way to go about things, even if there chavs or what ever, if they speak civilized to you respond in a civilized manor. If they demand things ask them why or demand they do things, if they are being complete dicks, be a nob back. That saying comes to mind 'do on to others as you do on to yourself' If they treat you like shit they must want you to treat them like shit.
