That is a very smart soldier! But wow, I bet she is wondering why he needs to take $100 a day from her account. That would add up to a lot of money over time!
I have a recommendation to help you with your writing. Be sure to carefully read it before you post. You will most likely notice when you have an error, and can fix it before posting. For example, this is an important part of your story, but the words are not quite right:
"Do you what this message signal"
Good luck and keep writing, @supo1.
