If they are nice then I assume it's because they are nice, not because they are doing it for money, since there's no direct obvious correlation. (Especially if they don't own the business.)
Prostitutes are payed to be nice, that is their service so the nice bit is "unauthentic". Just as the gardener might not be cutting my lawn for love, it's probably just money, but the friendly conversation probably is real.
Once you start tipping the niceness is much more out there as possibly faked.
Simple statement to me.

What you mean by "faked"? I don't want each of these people to become by best friends forever or have deep emotional relationship with me. I don't date them or plan to spend a romantic vacation with them. I want them to be polite, courteous and helpful. How can it be "fake"? How you distinguish "fake" please from "sincere" please and what that even means?
Being nice is to stand around after the job for a chat.
