Honestly UE I see this kind of charging happen at times and people act shocked. If a company gives me a CC and I use it to charge a porn movie, but then don’t expense it to the company, I fail to see how I am defrauding anyone. However if I am active-duty using an american express and do the same thing, I am somehow defrauding the public. Now certainly if I don’t pay the bill I am defrauding the people, but otherwise, it was just a medium. However people get nailed on this kind of thing all the time.
Where I work using your personal card to charge flights is VERY frowned upon, even though most want to do it for the miles.
