Generally, FAs are excellent and put up with more than I would in the same position.
I’ve been flying as SLF for over 40 years on airlines all over the world; and have only once experienced a rude member of the cabin crew (on a very large British airline). I was boarding at Geneva with a smallish rucksack (not my usual type of baggage, but I had just climbed Mont Blanc!). As I moved down the aisle, I accidentally banged the arm of a fellow passenger. I apologized and carried on to my seat. As I passed two female FAs, lounging by the galley, one of them, in a loud voice, said to her companion “Some of these bl**dy passengers should be in the hold with their bl**dy bags”.
What she didn’t know, was that at the time, I was working as a consultant to the Board of her airline. I didn’t report her, but I sometimes wish I had!
