I'm sorry you were treated badly but most of the immigration officers are businesslike. I do prefer to carry a paper ticket and boarding pass.

You will have to collect your baggage at DEL and recheck it but this is easy especially if you are flying Business Class. Once you exit the baggage area, take a left and look for the guard at the end of the hall. He will check your boarding pass then you will take an elevator or escalator to the Air India check-in area. Go the the Business Class line, where there is usually no wait, check your bags, go through Business Class security (also no line) and head to the Air India Lounge for breakfast.

I'd rather be doing this process at DEL than at JFK, ATL or a lot of other airports.
