This does not really have to do with WINE service, and I know the pouring issue has been dealt with before, and I have probably related the same story in a previous thread, but I think it bears repeating (well maybe not).
Recently many restaurants have jumped on the gastro-pub bandwagon, and now offer premium artisinal Belgian ales and micro-brews in addition to wine. I think that is great, and I love to experiment with food/beer pairings. The problem is that very few servers have been taught proper beer pouring skills. Even more than with sparkling wines, the method of pouring a beer is an essential part of the service. Moreover, the proper pouring technique varies with beer styles.
More often than not, I find when I order a $12 bottle of beer in a restaurant, the server just slops it into the glass, with total disregard to technique. Sometimes this causes a huge frothy head to form, or causes the beer to go prematurely flat. I much rather have a waiter leave the pouring up to me than trash an expensive brew. Even then, I have had problems. On more than one occasion, after carefully and gently pouring a bottle conditioned ale into my glass to avoid stirring up any residual yeast from the bottom of the bottle, I have had a server come up without asking and dump the leftover sludge into my carefully poured glass, then whisk away the empty bottle.
Here is a link to a pretty good primer on properly pouring beers.
