What's the most insane price you were asked to pay for a service?

My ex boss wanted to make an app out of the company website.
The site was already mobile friendly, so the app would have been a basic container, as if it was a browser opening the site home page.
He contacted a random developer for a quote and they asked $30000 for such an app.
However, they recommended to make a native app instead, in that case the price would have been $150000.
Needless to say, no deal was made.
So, did anyone ever try charge you such an insane amount of money for a simple service?

It's normal in the corporate world. People ask for millions to do something worth 10 times less.
