Precisely. When I studied over there, one of the few Dutch phrases I learnt was 'bier mit nee schuim' - basically 'no head'. One barmaid told me that if she served beer as I wanted it to a Dutchman, he'd refuse it.
The trouble with the Dutch beers is that when their glass is half full, there's half a glass of head on the top! You never actually get a full glass in Amsterdam.
