I appreciate all of your replies. Here is what I've decided to do. The owner is not all that friendly, herself. She's a "know-it-all" kind of a person, so I don't feel comfortable sharing what her son did with her. She's not rude, but she's just arrogant (likes to finish your sentences for you; has a story that's better than yours; thinks she has the answer for everyting quilting related and can't possibly learn anything new from anyone else.) She's not 100% my cup-o-tea, but she's tolerable. I can't imagine that we'll ever be good 'quilting friends' but I can maintain a professional "business" relationship with her if it means shopping conveniently and comfortably in her store.
If her son ever 'waits' on me, again, I will bring as many bolts to the cutting table as I want; and if he refuses to cut my bolts the way I want them cut, I will walk out of the store and never return. I will look for a sign, the next time I'm in the store, and see if there is a written policy for 'minimum cuts.' If there is, I will abide by it. If there is not one and the son is rude to me about it, I will take my business elsewhere.
I will also watch and review EVERY receipt I get in the future. If they will not refund my money or make it right, I will report them to the Better Business Bureau.
There is one gal who works in that store who is awesome. She only works on Thursdays, though. I want to shop there only when that gal is working; but if she's not there, I'll just have to keep a closer eye on what I'm being charged at the register.
Again, thank you for sharing your thoughts. I have such low tolerance for nonsense, and I don't like getting into arguments with people. The store employees have a choice. They can treat their customers well; or lose them permanently. I always will have the upper hand. There are enough stores in this area (not to mention the Internet) that I can easily take my business elsewhere.
