This is also known as money laundering... which can be illegal.
this money is legit though xD i swear money laundering was where you got illegitimate money and then laundered it through a legitimate buisness(front) which then turns it into legit money that can be spent... correct me if im wrong
edit: i just read and thats kinda what you see in the movies xD so ill try a better example like:
if your self employed and your friend gives you illegitmate money how you can wash it down(hide it within legit money) and give it back to him this would be money laundering
but what is going on here is just literally a favor as the v.a.t and stuff has been paid on that card
