Great idea. My dream, female-oriented shop would employ a trained bike fitter. It would be even better if that fitter didn't charge and arm and a leg for his/her services! Thankfully, we have just such a shop here in Indianapolis called Nebo Ridge that has a great fitter. They also have an expresso bar and carry my favorite brand--Shebeest.
Whether a shop is run by women or men, I think the trick is to create an atmosphere where all types of riders and both genders are made to feel welcome. At Nebo Ridge, the coffee bar is right in front of the maintenance/service area and they really encourage the bike geeks among us to shoot the breeze with the staff. They have never talked down to me and have encouraged my obsessive curiosity with all things bike-related. I wish I could say that about some of the other shops in town.
I think it also helps to create a sense of community from the shop by, for example, offering weekly rides. Obviously, that creates some business traffic too so it's a win/win.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
