This is a bit of a tricky issue. On one hand I can understand a business owner's wish to have the business and its employees fit a particular image. On the other hand, when you hire people to do a job you are generally paying them based on how they perform the tasks assigned to them, not on unrelated characteristics. This creates a slippery slope. So the manager wants an image of beautiful women wearing makeup but that can then be taken to beautiful
white women. I've always had a bit of an issue with companies that seem to prioritize personal attributes, characteristics, and lifestyles over what is required for the job.
Most customers want to go to a restaurant for the purpose of receiving good food and quality service. If the girl looked cute to begin with and was a good waitress, then there is no reason for her to be fired because she didn't wear makeup. Additionally, what if the girl had allergies and didn't want makeup due to skin issues? Now the company is meddling over her medical rights. Sure she has a right to find another job but a person is afforded rights whereas a business is afforded privileges. Since business is a huge part of the economy and has such an impact on many lives we have regulations that ensure that people run businesses in a way that is ultimately beneficial to the society instead of parasitic. Sure the goal of an owner is to make a profit but again it is a slippery slope.
I'm rather sick of how institutions always make it their business to govern people's private lives. When practically everybody is doing it, finding another job isn't easy. It has gotten to the point where even getting a simple job requires not only an application, resumé, and cover letter but a criminal background check, drug test, credit check, and full background investigation. Most people simply accept that it is normal to reveal one's entire private life just to flip hamburgers for minimum wage. In many ways 1984 is already a reality. I have already been routinely questioned for growing my hair long at my company even though we don't even deal with customers at our site. Again, prying unnecessarily into private lives and habits. Enough said.
