Being an Indian, I don't like the way we Indians use the English. Of course I also make mistakes, but I will try to learn from time to time.
I see and hear some phrases like, Please do the needful, Years back etc which are absolute blunders, I was wondering if Single Sitting is also Indian made ;)?
(Actually I am pretty sure it is Indian made :D ) Generally we hear this phrase as in http://goo.gl/y3gl06.
By Single Sitting we Indians mean the job attached to this phrase can be done in single visit.
