h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Whilst the precise nature of the theme may be elusive to the more casual researcher, I can categorically state that the themes adopted are demostrated by the following:

1) Ensure there is little or no seating, as more people per square metre can be packed in if standing, hence boosting profits.
2) Sell characterless beers at exorbitant prices, hence boosting profits.
3) Sell pathetic imitations of foreign foods at similarly high prices, whilst performing the particularly British excruciation of "ingredient substitution" on them (cf Hogshead, Swindon - Winner of the 1999 "No bugger'll notice if we use mayo on the nachos instead of sour cream" Award), hence boosting profits.
4) Stage mock fights on an hourly basis in order that the punters - usually, but not exclusively male - can strut about in some pathetic alpha-male delusion, hence increasing the appeal of the barn, hence boosting profits.

Spot the theme yet?

Ah what a precise precis of the social aspect!

Then again, that precis could be applied to many pubs, theme or otherwise.
