"Hi! My name is Lisa, and I am a gynecology student at Medical University - is it all right if I do your exam today under the supervision of Dr. Dude?"
Me: "That's fine by me!"
"Hi! My name is Lisa and I am a certified hair stylist, here is my state-issued license! This is my orientation week here at Discount Cuts R Us - would you mind if I did your trim today under the supervision of That Stylist Who Has Been Here Longer Than Forever?"
To sum up: Apparently I have no problem with a student using my cervix as a hands-on learning experience...but have CONCERNS about a fully graduated hair stylist nicking a quarter-inch of fur off my head under supervision at a DISCOUNT HAIR-CHOP SHOP.
...I don't think I want to know what this probably says about me...
