It's actually sexist and discriminates against men, the reason is very clear. First the man with a beard is no different than the hair on top of his head. It's just on the opposite side of his head. That's almost as bad as telling a man he has to have hair when he is normally bald. Keep in mind I don't have a beard and couldn't grow one even if I tried. So here is the real kicker. They would never tell a woman to cut her hair short like a man to be a manager. What if they told a longer haired man to cut his hair but not a woman? Lastly, managers do not serve food on a normal basis, yes once in a while but only under dire emergencies because of waiters not showing up. I was an engineer a while back and was offered a good job if I would cut my hair, I simply replied, if I was a woman would you ask her too? They replied "of course not" and I replied that's sex discrimination. I walked away from that one and was so glad I did. Made better money at another business with long hair. Some people are so stuck in their beliefs and can never accept change. BTW, no I do not have long hair now and through out the years I have cleared the 6 figure income three times. PS, where food serving/preparation is involved most cover their head and beard if they have one with a net including women.
