I normally don't mind FA's not being super friendly.

However, after a hellish week today, as I'm flying home on the last leg of my flight, even though I'm sick, and feeling totally worn out, I try to have an upbeat attitude.

As I board the plane, I see a young female FA. I give her a big smile and say warmly "Hi, how are you?"

Nothing. A blank, cold stare.

During the flight she performs her duty without any enthusiam, even almost arguing with another PAX - although that PAX was a bit demanding and not too compliant with instructions.

After we land, as I walk out, I smile warmly again, and say "Thank you very much!"

Nothing, another blank and cold stare.

I've encountered all sorts of FA's, but most are sincerely helpful, and at least pretend to care.

Never met someone so unenthusiastic and cold. As I was walking to the curb at the airport, I'm feeling extremly sorry for that FA. How sad to be so unsociable when you have to deal with the public...
