You get that in areas where almost all the pubs are tied to a few big suppliers. In our area, we've got whole streets of chain pubs and any number of Wetherspoons, and small pubs are dying like flies. So obscure beers aren't scarce but friendly pubs are.
Different branches have different local priorities for what to applaud and encourage, which is sure to be reflected in their GBG entries.
And branches in tourist areas presumably allow for the needs of visitors to their area, but we don't, because who'd want to come here?
