In fairness, that's what organizations like MI-6 and the US intel community really want for field operators. They don't want flamboyant tuxedo-wearing playboy types that light up the room the second they walk through the door. They want normal-looking (yes, sometimes even ugly) people who others wouldn't bother to give a second glance to. They move through crowds the easiest and get their mission accomplished without anyone noticing. Pretty Bond is total bullshit fantasy.
The Master of Disguise, by Antonio Mendez--the guy who ran the Canadian Caper that was later depicted in the movie Argo--is an excellent read on this subject. He and his wife were ideal undercover HUMINT agents because they looked like mildly overweight everyday American yokels, and as a result they were involved in some of the biggest intelligence operations in history.
