My wife and I have only seen one girl pizza delivery... person...
It's hard not to stare or say something about it, they (I mean females doing your job) are so rare. So, if I were you, I'd be afraid of people remembering the "female driver"
I know exactly. It's really awkward when little kids yell through the door "IT'S THE PIZZA MAN" and when they open the door their shocked and then their mom is like, honey it's a girl this time. ::shakes head:: OR they would look through the glass and yell to someone "IT'S A GIRL!!!"
Awkward stuff.
