Explanation
In Germany, patting someone on the head is considered patronizing and invasive of personal space, especially among adults. It is often associated with treating someone like a child or a pet, which can cause offense in social settings. Physical contact is generally reserved for handshakes or brief touches on the arm among friends.
Local Tip
Instead of a head pat, offer a firm handshake or a friendly nod to show respect and warmth.
