I can't say that I have ever really been given bad advice, but one time I attended a sewing seminar given by my Viking dealer. Several of the sales ladies were the helpers. I was hooping my fabric all set to embroider and the lady came to me and started telling me how to hoop and that I was doing it all wrong. Well, I threw a hissy fit; that I had been sewing longer than she was old, and was not a novice at machine embroidery; and thank you I will continue to do it the way I have been. A while later she pulled me in a corner and apologized. She didn't realize "who I was" and that I had more experience than any of the sales ladies. She evidently had been overheard chastising me by someone who knew of my knowledge of machine embroidery.
