Yeah, it is security theater, but other countries are way more relaxed than the US, especially small airports with few international flights.
When i was ~17, i had a friend with a false leg, with metal in it. We were late to our plane at a Moroccan airport (Agadir i think), we burst through the scanner gate that started beeping. He looked at the agent, tapped his leg, the agent made a "you can go" sign and we managed to get to the plane without any issue. I have seen very similar scene at Porto, it might be the mediterranean temper but i really think it has more to do with airport size (Lisbon airport agents seems more thorough)
