Spice Jet Airlines — behaviour of staff

My name ezhilarasu ramalingam.
I was waiting to board the flight on 9/6/18 at 5.55pm (Delhi to chennai sg103) at delhi airport. One of your team member (Woman) was explained something to one of the passenger regarding the reason for flight delay. I didn't aware of what she was saying. Before i reached that she has completed her conversation. I asked her what's the problem. She simply replied to me that she was explained everything earlier which was told to other passenger.
This is not the way to responding to the passenger. Kindly warn her regarding how to behave with the customers.
