I do, normally. The price of each wish is exact, and once someone says what their wish is then I tell them the price. Then they decide. It's not a real Payment if the person doesn't understand exactly what they are paying!

[Honestly he's offended here. Way to crap all over his business, Shura.]

And before you bring it up: the cost of a glass of water is inconsequential enough that I would have been fine waiving the fee. And I haven't told you a price for your real wish, because you haven't told me what that wish is!
