Theft???

This Would Be A Ridiculous Question

When I visiting AF shop >> Bank

I saw this sentence :

"Gil Protected From Theft"
1. What that sentence mean??

2. Who would be the theft?

3. And Can you teach me how to theft a gil? :D

You can't steal anymore, so it's completely useless.

I see

Don't worry.
AF is just really stingy with it's money.
