Maybe smoking more? I would say that smoking (tabaco) is more common for my European friends, than my American friends. But most of my European friends are French, and most of my American friends are from the Bay Area, so it is more probable a California vs France than American vs Europe
Reminds of a friend of mine who got out of the ICE for a smoke and it continued without him. Didn‘t have his wallet on him either so I had to drive 200km to pick his dumbass up from Berlin.
