What's the point of a random person telling another random person "hello"?

You know like when you're walking down the street or something and as you walk past this random person, they just say, "Hello" or "How are you doing?"
Are they just being friendly or is there some other reason behind it?
Some people are just that friendly
It's some people's way of shooting their shot
There could be another reason for it
I am that person

The one guy at Dollar General did this today and I go there several times a week and he never says anything. Now I'm wondering if he's just in a good mood or if I'm looking good today. 🤨😂

I could be reading too much into the situation, but I just found him to be unusually friendly.
