Short of the finger printing they do about the same to Americans returning home. I went to Oktoberfest in Munich several years ago and couldn't believe how easy it was to leave, how easy it was to enter German (they were very nice, took 5 minutes tops), and how much of a pain it was to get back into the US. Apparently 2 mid 20's males returning from Oktoberfest was suspicious and required 20 minutes of backpack searching and questions (not an interrogation by any stretch but still annoying).
