Britain has some customs which are different from other countries, for example, did you know that in Britain most people have THEIR milk delivered IN their homes early every morning. AT night they put their EMPTY milk bottles outside THEIR doors and in the morning the milkman takes the empty milk bottles away and leaves full ones in their place. You CAN buy your milk in the supermarket or local shop, if you prefer, but a lot of people ALREADY like to have it delivered. They only problem is that SOMETIMES little birds drink some of the milk if you don't cover the bottles or get up very early
