On quite a few occasions in the past, like many of you, I have witnessed cabin crew walking down the cabin with an insect spray in either hand. They say beforehand that it is harmless and that you should cover your mouth and nose if you so desire. I always do because I don’t like breathing in these things, but, for cabin crew who have to do this on a quite a regular basis, how do you feel about it? After all, I can cover my mouth and nose but you obviously cannot. Just interested!
