When I used to work in plant / tool hire, collecting lawnmowers from customers,
there was the greatest struggle to get the paperwork and out the door first,
every time it would be a woman, with a broken heart sob story, but they
always settled their debt, the lawnmower came back, the driver smiling and happy.
No money ever changed hands.
So no, I would never work for anyone without the majority up front and the rest
stuck in their drive so they had to pay to get in and out, or some other leverage,
its terrible to have to fight for what you earn, but lots of customers will try,
and lots get told no am busy, because their name precedes them, and some
get told, its on me, because they need a break.
