Being an American living in London, I fly back home to the states several times per year to visit my family.
I've used all different air carriers and all different routes- I go for cheapest, but mostly Delta.
Anyway, I've seen and heard many, many derogatory remarks made to the cabin crew from passengers. I dont know how or even why they have to take that crap.
If it was waitress, they'd probably end up spitting, (or worse) in the food.
So, I understand that guys frustration. It probably built up over many trips and he just couldn't take it anymore. Just like a 'real bad day at the office' LOL.
I think he deserves an apology from the sob passenger and I was also thinking his union should be sticking up for him.
There is no way passengers should treat air crew in this manner....NOT acceptable- IMO.
