Kiss-kiss-kiss vs kiss-kiss

It's quite interesting how different cultures greet. Here in Switzerland as soon as you know each other a little bit you kiss-kiss-kiss, left-right-left. The two Italians I met the other day on the other hand kiss-kiss only, right-left. You can see the problem here? Yes, we almost collided kissing straight on the mouth. Which is funny considering we had only met the same day...
