LOL, luckily it happened only once, but I had a client who had to get a logo vectorised - old building of some sort from 50-60 years ago. Had a logo on it like a sailing club's or something. Not to mention, it had to be vectorised for a CNC engraving machine, so had to be single line, optimised for a 0.5mm v-cutter or something. So I had to keep as much detail as possible for that cutter - while making it all work.
"Can you do it?"
sure... have you got a file?
"yeah I do... don't know if you can use it..."
I can do anything (this is when I first started, thought I was superman)
"ok... here it is... "
sends me a low quality photograph, of the logo on the side of the building... from an ANGLE!
I reskewed it out best I could with perspective tools, and redid it in coreldraw.
The only thing I sort of did right in the whole transaction, was my price I think (was barely enough though IMO).
I had one the other day...
"doesn't the computer generate that cut line by itself based on the graphic inside it?"...
