Yes

Lucy didn't mind the idea of a tongue piercing, and it was $50 more on her account. So, she picked "Yes" and almost immediately she felt a strange sensation in her mouth. With the selfie camera she looked at the change and could see a barbel piercing through the tongue. It was done and it was painless.

There was no other explanation than magic, and her account increased by $50. It was a miracle of sort.

Going downstairs to eat, Lucy did her best to hide her new jewel from her parents. She didn't want them to freak out.

After doing the dishes with her mom, she walk to the book store to find a new one to read. She got $75, she can allow herself to get one. The clerks, a woman few years older than her, knows her well.

"Hey! How are you?"

"I'm good. You got something interesting this week?"

"I have something that may be of your taste. Silver light. A fantasy romance."

Looking at the book, it seems indeed to be an interesting read.

"I'll take it." She said.

More acute than her parents, the clerk noticed the piercing.

"It's new?"

"Oh, yeah. I got a weird app that offers change for money."

"Be careful, it may be some kind of con."

"I don't think so."

Lucy took out her phone to reassure herself without exactly knowing exactly how, and noticed a new question.

"Look, it's like that, and I didn't even added an app for it!"

Would you double the effects of the last two offers for $100?
Yes/No

"What a weird question, like it could grow your tongue, somehow."

"It can! It's what gave me the piercing and a longer tongue. Look!"

Lucy showed her tongue, which surprised the clerk lady.

"Come on you're playing with me!"

"No I swear!"
