Two items:
On my last visit to Dubai, I departed via RJ to Amman. The ticket agent sold me a nonexistent seat on their 1011. Is it possible that the present "some disagreement about seating" is related to my experience?
And where does one seek information about what drugs (prescribed or otherwise) are banned in a particular country? FWIW I'm sure Abu Dhabi and Dubai have different banned lists, even though they're both UAE.
