I did this briefly years ago for a hotel chain (the booking, not the stealing). We got an extra quarter for everyone we transferred to another department for deals or some shit. We were supposed to ask people if they would like to hear about it but I found out that as long as it transferred they could immediately hang up and I still got my bonus. After that every caller I had got transferred to the other department for the rest of the time I worked there.

I made an extra few hundred bucks and got canned about the same time I found a job in my field. No FBI involved, though.
