The lady who interviewed my father was very rude and disrespectful too, she didn't even ask him nothing,just gave him passport back, and thats it,
All she needs is money that people spent for the interview. maybe 5 people from 100 are lucky.This is the 4th time my father tried to obtain a visa to come and play with his grandkids... Really Really disappointed!
