I'm a 24 year old waitress at a cafe. And I was just wondering how I can come off as more seductive, and flirty (particularly for a certain regular customer I've had my eye on these past weeks.) But still remain low key and professional. I know it's not the most 'taboo relationship' but....

I've talked to other friends/waitresses about this subject and they also seem to have some trouble finding that proper balance between letting a certain customer know your into them without making it seem like your just a typical friendly waitress or worse that your only behaving that way just for a bigger 'tip'. What's a good way of showing a customer that your actually into them?

Any guys or other waitresses with experience with this subject would love some from feedback from you.
