In-courteous & rude staff @ Bali

I was flying from Bali to Singapore and the staff was really rude and in-courteous while we were checking in for our flight to Singapore. On top of it, he was talking to his colleagues making fun of us in his local language thinking we are foreigners and would not understand that but thanks to a local passenger behind us who told us about the same.

We really had a terrible time and I will never travel with Jetstar again.
