At Johannesburg airport this week the security took my bag of reading material to one side and said I had a "fok". She repeated it several times but I hadnt a clue what the problem was. She raked around - ignoring the liquid (facial spray) - and pulled out a telescopic back scratcher which I wasnt aware I had with me. She showed it to her colleague and they decided I could keep it. Security is always a bit of a mystery. Tea bags and dried soup will be fine, but anything not needed on the journey better in your checked in luggage.
One hopes it's the airport you are travelling TO and not the one you are going from?
You can take all manner of things out, but whether or not you are allowed to take them in is completely different
