A lot! Sometimes 50 dollars for some stupid form that has no bearing on what they’re trying to do.

The rationale is probably something like "Yes I have to pay $50, but it will save me from paying $2000" which sounds great, but critical thinkers (of which these folks are not) don't realize this is the same thing as:

"If you give me me your cow, I'll give you these magic beans" from the tale of Jack and the Beanstalk. The difference is that in real life there is no beanstalk, just a handful of beans.
