The call center beverages seen in "Slumdog Millionaire" appeared to me to be some sort of hot milk+tea beverage. At the time based on sources I had already read, I thought this would be spiced. I remember that in the movie, each serving was in a decent size drinking glass of about 10-12 oz and the glass was wrapped with what appeared to be a paper napkin. For some reason this is stuck in my mind.
