Do people know their partners anymore?

Ive noticed over the last few years, people always posting or asking in stores, "whats a good gift for my boyfriend/girlfriend?"

I used to work in a department store and got asked it all the time, and the answer is always the same, "I have no idea, what do they like?"

I know my girl well enough that when Xmas/Birthday comes around I remembered stuff she wanted, certain things I know she'd enjoy and in some cases went to great lengths to get something original I knew they would love, based on the fact I listen to her over the course of the year and learned who she is.

But people just tend to go with whatever is generic: Perfume, Flowers, Chocolates, a shirt, a scarf.

So I wanted to ask, does anyone here still know how to buy gifts for a loved one?
