As a fa, I've never forced to share a hotel room, but I've got a good story...
When I was a new-hire, I had a layover in PDX, and when we arrived at our hotel they asked us if any of us wanted to share a room, as they were oversold. They were offering $50 to each of us. Luckily, I was flying w/ someone I had just gone through training with and knew well. I told the desk clerk to make it $100 each and he had a deal.
So, after 7 weeks of unpaid training, I took $100 cash to share a room w/ a friend. Win/Win
