Years ago an acquaintance was running a MICROS POS for his restaurant, and lamented the heavy tax burden the local government levied on him.

I was able to create an external software application (we called it "CookBooks") that would selectively skim off cash transactions (ignoring credit card transactions) from the Access database.

This allowed him to reduce his tax liability and pocket a substantial amount of cash on a nightly basis.

This was in 2002 and I recall that it took no time at all to gain update access to the underlying proprietary Access database powering the MICROS system.
