This is not the only drinker-dependent phenomenon I have noticed.
Australian beer is always gassed, and something similar happens with the foam that forms the head.
Many drinkers end up with the full head of froth in their glasses when the liquid is consumed while others seem to 'kill' it after only a few sips. This appears to be independent of the beer brand. I have been told by several bartenders that glasses should never be rinsed with dishwashing materials as these kill the foam. This happens with all brands, as far as I know. These have two essential properties.
