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

For some peole the accepting of drinks from strangers is habitual and generally sought. However according to the Intergalactic book of etiquette you should be careful not to offend.

"On some parts of the planet earth the giving of alcoholic drinks ties the person into an invidious social practice called The Round. This can cost the stranger many times more than the value of the drink which was bestowed."

Wierd huh?

"On Vrissked II the person who gives the drink has the right to marry the receivers first born of either sex."

While on Bblugg:

"... the recipient of the drink, having no previous knowledge of the person is safe to drink it but a second drink - now that some sort of relationship is formed is deadly poison. The antidote to the poison is having no feelings whatsoever about the giver. Once any sort of relationship is formed the poison becomes active."

beer - the drinking of it and appreciation of being drunk is a universal language

Unfortunately the language is often garbled, hic.
