The dish on chicks

First of all, as a tutorial on pc etiquette, you're living in the dark ages if you still say "waittress". They are now servers, whether male or female, just like actresses are actors. But starlets are still starlets? I digress.
As a woman and mother of two daughters who were once upon a time servers, I'm surprised to have arrived at this point of view...but I wouldn't hire a female server again. I have had female servers who were experienced and knowledgable but were liabilities in many ways. They wiggled out of physical work like lifting and moving tables or changing the 50 lb boxes of soda syrup and one could only carry two plates at a time. A real liability on a busy night. The ones who were not teenagers were single moms with myriad problems. They'd chitchat to the kitchen staff about selling their eggs to pay the mortgage, escape to the ladies room to go over homework via cell phone with their kids for a good 20 min., be doubled over by the coffee machine with menstrual cramps, etc. Men have that mentally unhealthy skill of compartmentalizing which makes it frustrating to be in a relationship with them but makes them focused at work. The female servers I had showed up at work dragging all their problems with them.
A certain amount of flirting with customers can increase a server's tips but I had one who went way overboard. She told us she had once been a stripper and saved her biggest smile and best wiggle for male clients. Several men came in pricipally to see her. When she quit, I lost their business.
Women in the kitchen have been no problem. But in the dining room, it's men only.
