The froth on beer (also called 'the head') is a good small talk subject. With the exception of Guinness-type beers, the British can get upset if there is too much froth. They think they are paying for bubbles and not for beer.
TIP: Warn the British that a Pils or a Weizenbeer needs a lot of froth.
Paul Smith
