Hello how are you today ?
This is more of a “make yourself comfortable” statements. Answer with a pleasant smile. If you had any trouble during the day, don’t hesitate to mention it. But make sure you express it in a positive note.
Examples:
– “I am very well today sir, thank you”.
– “I am very well today sir, just that the traffic here is bit of a hassle. But I made sure, I start a bit early to beat it.”
