I can understand why they ask for a deposit. We have a small snowmobile repair shop, and I can't tell you how many machines we end up with at the end of the year that the people haven't paid their bill, which means they haven't picked up their machine. We have to buy the parts needed to fix it, but then they don't want, or have the money to pay us. We are out the money, and time we put into their mahcine.
I can see both sides of the story.
