Capt. Cynical:
I can assure you it has little to do with any medical condition, rather than the propensity here to cause maximum inconvenience to anyone viewed as being in a service position:
Once on board, press call button and ask for water (never mind we've just come from the terminal with water available everwhere), then press call button for another newspaper than the one the airline has already placed in the seat pocket in front, and finally.... oh yes, let's press the call button again and ask for cotton wool, just for the hell of it.
