Dutch New Year Tradition

I learned a new Dutch tradition today - upon seeing someone for the first time in the new year, it is traditional to shake their hand and say, "Best wishes in the new year" or something similar. (Everyone returned to work today from the holidays, so there was a lot of hand shaking going on.) At first I stuck with the more familiar (to me, anyway) "Happy New Year!" but by the end of the day, I was giving people "best wishes" as well.
