I used to visit a Portuguese coffe bar/pub in Thetford. (It operated mainly as a coffee bar during the day, serving cakes, coffee and light meals but it turned into a pub, for the local Portuguese community to enjoy their Sagres and Superbock, in the evenings).
One of the things I loved about it, and I soon learned to join in with, was that anyone entering the place would immediately go around every table and shake the hands of all the customers, greeting them warmly, and then do the same thing again with everyone standing at the bar and with the proprietors. (It clearly didn't matter if the two people shaking hands had never met each other before). Only then would they place their order.
I often wished that we Brits could be as convivial and, indeed I still do now (although, admittedly, not quite so much so right at the present!)
I'm never really that keen on being hugged and kissed by a Scots friend of mine though - but I'm safe enough from the possibility of that happening for a while anyway, as she lives in Northern Italy ;-)
