Is a normal, young person with manners really rare as I'm told?

Just last week, some elderly woman was taken by surprise upon seeing me opening the market door and helping her with the bags. She told me what I just did is rare nowadays.

It seems like just basic to me. Is it really rare?

There is really nothing special. It's just basic manners. Same as saying thank you. Yet a couple older person act surprised when they see that coming from me, an average 16 year-old in HS.
