I agree. This problem, as with so many "war stories" posted on this site, was a problem of your own making. If you want to be treated like a business professional, you need to act like one from the first interaction you have with a customer, and it shouldn't make a single bit of difference if it's someone who works with your husband or a stranger. If anything, you need to work even harder to maintain a professional business relationship with people you know.

I've done many, many orders for friends, and current and former co-workers. Every one of them knows that they'll receive a detailed written order confirmation with all flavors, colors, dimensions, designs, delivery details, etc., listed, and a statement of the charges and the date payment is due. If we're not sure about the design, I either draw a sketch or send sample pictures until we're both satisfied we're on the same page. If I don't make six of one design and 9 of another, I tell them I can't do that when they request it. I don't wait until the last minute. If they can't bring payment to me, they mail it.

If you act like a competent business professional, you're more likely to be treated that way, even by difficult or confused customers because they know they can't screw with you, and they have confidence that you're in control and they're going to get a presentable product. Know what your expectations are and communicate them up-front.
