Certainly SFO, my home airport, does it countless times with no questions whatsoever. I'm very certain SJC was fine too. In fact, I had no problems previously at LAS.
Thinking about this a little more. I went through some airport recently where I literally forgot to take off my shoes. I passed through the metal detector, then realized and was never asked anything. Not sure if that was LAS or not.
