Over thirty years, this has sadly been an all too often observation for me. But I'm talking about other pilots. And that's quite often followed by a downwind takeoff. Why would you want to do that? Saving fuel?
So perhaps warm the engine correctly, take off into wind and lean to LOP in the cruise...
