I once left a spare passport and a no-longer-binding wedding ring in a two star hotel in Prague. The spare passport I’d left with the front desk to guarantee payment for the room service meals and champagne I'd bought for the girls. After a week, I felt sunlight for the first time in seven days when I left from the hotel I settled the bill half in cash and half by negotiating a price for the old passport. The ring, I expressly traded for an arrangement with a girl that was for me gratifying, enough, and for her fiscally rewarding, on some level I'm sure.
