I work as a freelance sales trainer, I have a track record going back over ten years and clients that use me over and over for training new sales people. I charge a set fee for the training and then a percentage of the sales achieved by the person over the next two years.
Last year I was approached by a start-up I had never heard off who asked me to meet with them.
Client: I won't pay cash, but I can pay in stock in the new company.
Me: Well I'm sorry, but if that's the case this meeting is over. That's a red-line for me.
The CEO physically stopped me leaving the room and said if I didn't reconsider there "would be trouble". His head of sales said, "You better listen." I'm a former Royal Marine and pushed him to the ground, and left the room.
He later called the Police and reported me for assault. The Police laughed when I told them the story.
