Anecdotally speaking: My friend has a "wunderstick", which is a hand made walking stick. When we go into bars in Germany, he taps it, and the bartender gives us free drinks. Before we leave, he taps his stick again, and says some big speech in German (about how grateful he is, etc). Most bars and hotels cater to the journeymen quite well. While we were in Berlin, he also had girls run across the street to him and kiss him on the cheek or lips. I guess it's good luck to kiss a journeyman.
