Ali Baba recounts hilarious airport experience with Cossy Orjiakor

I couldn’t get the humour initially until I read through again. He shared the photo above and said;

So @cossyojiakor and I were on the same flight to the USA last month… I had crossed Immigration and even checked in and realized she had not called to say she had checked in… called later and found out they held her back at the airport for 2 hours. Why? I asked her. She said they said something about “No dairy products allowed”... Still don’t get it.
