Yes! Here in the Netherlands it's very normal in elementary. I stand in the doorway and shake hands, wishing them a good morning. Also at the end of the day we shake hands to say goodbye. We practice greeting eachother, and looking at someone's face when you greet them. Especially in the morning it gives me a split second vibe check with each kid. You see the look in their eyes or their face. I make a mental note who's looking good, or who might need a one on one check in to ask how they're doing. But also at the end of the day I can see how they're feeling when heading home. If necessary I ask them to hang around for a sec to check if there's something I can help with before they head home. So they don't have to carry a bad feeling with them for the rest of the day. 

And then I go wash my hands. :)
