Almost every Indian I know (including me) mixes at least two languages in their daily conversations seamlessly, that too within a sentence. Westerners may find that Indians talking among themselves in their native language(s) drop English words out of nowhere. Again, I can't imagine this to be a uniquely Indian phenomenon. Multilingual people would be doing this.
Lingual purists may find it irritating, but I love such mix-ups!
