How much cash do you give the wizard?!

Question:

How much cash do you give the wizard?

---

Lets say u meet this wizard. the wizard says he can make you more attractive if you pay him money. when you ask how this works he points at a random stranger and says, " i will now make this person 1 dollor more attractive." he waves his wand as far as you can tell nothing is different. but somehow this person is suddenly more appealing. the difference is invisible to the naked eye, but you can't deny that this person is vaguely sexier. the wizard has a weird rule though- you can only pay him once. you can't keep giving him money till your satisfied. so how much cash do you give the wizard?

Answers: all the cash i have on me. nothing at all! it's probably that spell he's been working on for the past too months! None at all 25 cents. i already am very attractive thanks to good genes.
