When you enter an airport or pass through an airport gate in any airport (in any county), many of the laws, rules, and regulations change. Kinda like a foreign embassy in a country. (in the US for example, when you just enter an airport, Federal law applies, not only state law). Airports are funny places rules wise. It isn't an unreasonable question. As a moderator, you should know that, and I am surprised by your response.
