I'm not reading 6 pages of this.
Either:
A. She was flirting and interested, but lost interest when you didn't reciprocate enough for her to feel like you were interested in her too.
B. She's a service-industry worker and it's her job to be nice to customers so they come back and/or tip higher.
In either case, this is why I always advocate for being direct. Saves you a lot of time and guesswork.
Fair enough, I know not everyone has time to read entire threads.
Another poster (on a past post) indicated the possibility she felt I wasn't into her (because I apparently didn't reciprocate enough). I'm going to tell you essentially the same thing I told him: What a strange world we live in where telling a woman she looks good is somehow viewed as a soft rejection.
As for the idea that she simply wanted me to come back more often, while I totally acknowledge that might have been her motive in complimenting me, it backfired on her. Thanks to the lack of a flirt session the next time I went in, I'm going to go back
less often than I otherwise would have.
