Actually many ppl in Indian cities speak at least some rudimentary broken English . This is because we just have so many languages (18 official last I checked) if you mean to have any conversation with a person who's from a different part of India you'll have to learn English . (Hindi is more prefer ant in Northern India but once you move out of a group of 5-6 or so northern states to the others pick up English . For example I speak English Hindi and 2 regional languages Oriya and Bengali . And my first instinct when speaking to someone from India is to start with English unless I already know where they are from etc .
Although here you could make a case for more Hindi too given the location depicted. But many Indians also combine both while speaking too

we call it hinglish . ( Plus speaking English can also be a form of showing dominance/ showing off in certain parts . But that's reading a lot into a small scene I think here the intention was Indians speak English so we can get away with using that)
And there are words in Hindi in that sequence .you hear it with that family quickly going indoors . And then Chloe also says nahi which means no to the guard. I fact the words she uses "sir please nahi" is an example of hinglish
Nd has seriously done it's groundwork . I hadn't noticed or paid that much attention to these things . Possibly because the whole scene seemed so natural to me. And now looking back at it within the context of comments in this thread I notice nd has included these small things which I take as very normal in India but may not be obvious to someone who's not indian . I think they've done their groundwork from the looks of it .
