Plorer---
You can't sue for defamation b/c defamation requires a written publication.
You can't sue for infliction of emotional distress unless 1) the conduct was extreme and outrageous, 2) the bartender intended to cause severe emotional distress, and 3) the conduct must have caused severe emotional distress. If you can prove all three of these elements, you would prevail. Most plaintiffs who have been humiliated will use this legal theory as their cause of action. However, infliction of emotional distress is EXTREMELY difficult to win on, and you would need medical/psych. records to back up your claim. NOt to mention the cost of litigation.
Unfortunately, there is no claim recognized under the law for public embarrasement, and because you were in a private club, unfortunately the guy had every right to ask you to leave. If the guy had touched you, then the facts would be much more favorable to you.
My best advice to you is to stop by the bar or call during the day and see if you can speak with the owner. You might even fire off a letter threatening legal action for infliction of emotional distress. (even though you most likely would not win---the owner would necessarily know that). Bluff the owner by threatening action and see if you can get an apology from him or the employee fired. Threatening legal action isn't against the law, only pursuing a frivolous claim is......
YOu might want to ask someone else trained in tort law for their advice as well---since tort law is not my area, most of my knowledge is with corporate/constitutional areas.
Sorry to hear about the incident, but to be honest with you the baretnder's actions don't make a lot of sense.....you probably had someone whispering negative shit aoout you to the bartender or maybe he was just pissed that you were the belle of the ball.
