I think the problem is more one of not being able to get back airside without much pain unless you have some kind of 'approved id'.
I've not suffered it too often but when I have it has always been with the guy who saw me walk from my aircraft past his desk and wants to stop me going back without an airside pass. I have an amusing story about a woman in a one piece lycra suit with a steel cable hanging off it and a security guard at Liverpool airport but its probably only amusing to me !
