I know the feeling. My machine was late as well. Which was scary at the time. I'm on the hook for a machine I ordered off the Internet from a company 1,800 miles way. Not to mention the idea of paying rent on my shop and no machine. It's a little late now to say this, but for other's out there, get a tracking number before you set up for the install. That way you know its on the truck. Even then you cant control the weather. Personally, I'd rather know my machine was waiting for the roads to clear than wonder if the truck ended up in a ditch somewhere. If your customers don't understand then screw them. Who needs that crap anyway. Once you get your machine it will all be worth it.
Hey, I got an idea

yum
Don't sweat it,
