Good challenge; I was waiting for it....
I know (not 'think') a few managers who own companies that supply the company with products and services.
A few months ago,I sent a proposal for service provision to KQ. The manager who received it called and asked me to add 20% to the charges for her. I said no ...and she said no to my proposal!
A former head of communications & corporate affairs was a founder & major shareholder of the company that handled advertising bookings for the in0flight magazine (Msafiri)

Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
