I'm sorry that's been your experience. I don't know where you live; and I know this can be a cultural thing.

But in America at least, it's not usually bullshit or false. It's not a means to an end. I will compliment servers and cashiers and receptionist just because it makes everyone friendlier and we all enjoy our brief interaction more than we would otherwise. It would be nonsensical to say I was using them. For what?

I am aware that there are cultures out there where nobody does this and it is viewed highly with suspicion. It just makes me very happy I don't live in one of those places.
