I know, actually that is the fkin' way to do this work. No really.
I just know if I had those machines, I better be centralized in one of about five regions, the only major cities in the US. Where people are so rich they think a thousand dollar check is like a twenty dollar bill.
They ask you how much. You say $20,000, and that you'll have 'er done in an hour or less or the bill gets bigger. I'm sure they come back with, "Do you want cash or check?"
Throw the combination code brief case in the pile with the rest of those things, and away you go to the next job the very same day. Plain and easy just like champions :spam::spam::spam:
HTH did you guys get the credit line for machines like that after all? A lot of years in the biz is my guess.
