They start drinking, then stop long before they are drunk!
WHAT'S THE POINT?!?!?!
If you don't want to be drunk, DON'T DRINK!!!
Cheek kissing. In most parts of France and Spain, men/women or women/women friends will great each other with a kiss on each cheek (the face cheeks!). But in some parts of France, they do two on each cheek. left-right-left-right. This even catches out those used to doing a simple left-right kiss.
Boobs <rude one following>: in Spain, it is seen as a little kinky if you put your female lover's breast in your mouth. Not like "Eurgh, what the hell are you doing?!", but more like "Hey, that's naughty!"... or so I am told...
In the UK, if you go to someone's house and they offer you wine, they will pour quite a bit into the glass. Not necessarily brimming it, but they will certainly pour past the halfway point. according to one anthropologist I read, this is because we abhor stinginess and therefore don't want the guest to think we are being tight with the wine. But, my experience has taught me that on the continent they pour a relatively small amount into the glass, then top you up as you go... so don't drive to a Frenchman's house!!!
Tea and coffee are incompatible beverages. Many Brits seem to think coffee should be served scalding hot, and many Europeans seem to think tea should be served luke warm and stewed. NO!
Properly-made coffee is at such a temperature you can comfortably take a big swig the moment it is placed in front of you, and properly-made tea involves rapidly-boiling water (something they don't have the hang of on the continent!). Don't get me wrong, you can
definitely get a
very good cup of coffee in the UK, but I am yet to hear of someone saying "Oooh, we had a lovely cup of tea in Rome!"
