I tell my parents that I am in no way a morning person. Sometimes I wake up 5-10 minutes prior to opening for the day. They are well aware of this when signing on.
I think this woman is being very petty. If she doesn't like it, in my mind she can leave! Like playfelt, I barely EVER wear makeup, so I just wash my face, throw on my 'daycare' clothes (comfy wear), and open the door.
