I would be sympathetic if it wasn't culturally acceptable to hire a women because she's good looking and before you tell me its not go to any major restaurants and find me ugly waitresses.
That's like saying you got hired because you are good at what you do so you can be fired because you are good at what you do. Makes no sense.
The employer was a coward. This is essentially the same reasoning that a woman invites rape by the way she looks and dresses and it's not the rapists fault for not controlling himself. Do we as men not have any control over what we do? Grow the hell up.
