I advise against approaching pretty working women who are in the
service line like pretty stewardesses and waitresses. You will come
off as one of the many, many, many, trying-your-luck harrassing
men. It doesn't work that way. When they don their uniforms, they
become a service provider and they are just working. You are just
one of the male customers, or whatever, even if you are a bystander
when you talk to her, she will respond as her role requires her to.
You will come off as a sexually-harassing disturbing and rather
corny man if you try too far. If you really want to know her, wait
until she leaves the working premises and change her uniform. You
know, totally out of that setup. Then you will know her as a
person. And she, you.
But anyways don't be amazed by pretty working women. It's the
makeup and hairdo and dress. Believe me. Make lotsa difference.
