I'd say about half the people in the Netherlands drink their coffee "gewoon" ("just")! Add too much milk and it's officially "verkeerd" (wrong). As in, coffee machines in petrol stations have a "koffie verkeerd" button, presumably for foreign truckers from far off lands where they spoil their delicious hot beverage with... (blegh) milk.
Our whole team interviewed a guy at a local restaurant over lunch. Normally the interviewee would order something simple because we'd be grilling them pretty hard... but this guy ordered the yak. What did it mean?!!?
