Tooth Fairy Rate Hike?

The son of one of my co-worker's pulled a loose baby tooth yesterday and put it in a zip-lock bag with a note on it. "Dear Tooth Fairy, This tooth was really hard to pull and was very painful so I think I deserve $20 for it." Haven't heard what the Tooth Fairy left yet but I thought this was very creative for a small boy. I know I'm getting old when I hear things like this 'cause I remember when the Tooth Fairy left a quarter and that was a lot.
