Hi @Gaurav , you are talking with adults and well educated people, this tone of talking is not acceptable at all. I believe you have issues in communication with people as many of my friends mentioned the same point to me before. My advice to you to work on yourself to enhance the way of communication with your customers to avoid more people hating you.
Anyways, I promise it will be my last time to join with you on carnity, I am not a pupil and you do not have any rights to talk with us in that way, but keep in mind that your behaviour will affect the carnity club reputation.
Hope to work on yourself and change your way of communication and know with whom you are treating.
