The level of touch that is acceptable and/or usual varies an awful lot from country to country and also from generation to generation.
When I was working in French speaking Belgium, I worked in an open plan office with perhaps 30 people in it. On arriving in the morning, it was obligatory for politeness sake to go round the room and give the women a kiss on each cheek and shake hands with all the men. The same applied when I worked in France. however, the number of kisses varies in France - in Orléans and that region generally, the tradition is four kisses whereas in eastern France and in Belgium, it is two.
That was not the case at all when I worked in Flemish speaking Belgium nor when I worked in the Netherlands. There it's no kisses and no handshakes!
When I returned to the UK after living in France for several years, people were slightly repulsed by the my touchy-feely ways and I had to revert to full British physical coldness to make myself socially acceptable again!
