No, they just hate excessive head that is inappropriate to the beer. Some amount of head is essential to properly release the aroma of beer. A traditional cask ale is hand-pumped and served without additional gas, so it will tend to have a smaller head than a beer that has added gas. No more than 5% of the glass should be filled with head. Many pubs use glasses with a marked fill line, allowing for space for a head while still providing a full measure of liquid. Northern drinkers traditionally prefer a thicker, creamier head and used beer pumps with a "sparkler" nozzle to provide this, while southern drinkers typically preferred very little head; this historic divide is starting to soften in recent years. Some European beer styles are properly served with a bigger and frothier head, particularly wheat beers and pilsners.
