Is it just because I’m being kind, or is there something more to it?

I recently moved to a new city, and it’s been a bit of a change. I’m not good-looking at all, but I’m nice to people. The thing is, when I ask for something small like "May I have some more sugar?", people always give it to me with a smile and say "Of course, for you." It’s like little things like that keep happening.

We got to a building, someone who helps me with personal stuff, introduced me to the owner's son.
He got complimented on his hair, so I looked at it, but I realized I stared a bit too long. When I looked away and my eyes met his, I caught him staring at me; he held my gaze for a moment. He stared into my eyes with such confidence.
When I looked away, he quickly smiled.
Later, I walked into a building with the person who was helping me with personal matters. She introduced me, and suddenly, this other person made coffee for me and held the door open. The one helping me mentioned that they never do that for anyone else and looked even shocked at me.

I’ve always been the shy, nerdy girl, which is why I’m asking this—these kinds of things have never happened to me before, but now these small gestures keep happening.
Are they just being nice too?
Why do you think this is?
