No, the accountant is going to ask "When the !$^_at_# hell did we get an account with AT&T?!" That particular example is near and dear to my heart; AT&T created a commercial account for me which they first charged $0.00 at set up. When I did not object -- I had just started a home computer line with them and -- they took it out ~$750 from m checking account without my permission.
When the gas gauge of my car says zero, that is an actual measurement using a ratio scale with a natural origin point. When I talk about putting gas in my Lamborghini, it makes just as much sense to talk about putting -10 liters into the gas tank. When something does not exist, then you can say anything.
Basic logic:
1) A false premise can imply a true or a false conclusion.
2) A true premise can only imply a true conclusion.
