I recently visited the Rain Bar in Manchester and asked for a taste of the seasonal beer, I think it was Razzmatazz. I was told by the barmaid that they weren't allowed to do that. She did give me one (a taste, that is) eventually after making sure the gaffer wasn't about.
Is this common practice in Lees pubs? I've never had a problem with sampling beer before buying it in any other pubs. Most will offer a sample if asked what a beer is like. It's easier than trying to explain what it tastes like.
Cheers, Lee.
