Origin:Dutch: Back in the 70s a ‘mobile store’ was generally operated by the local dairy store (or producers), delivering fresh produce and dairy products right in front of the door. These drivers (‘milkmen’, Dutch: ‘melkboer’) and their stores became popular meeting points for people discussing the latest rumours in the neighbourhood.
