a special sales person
I just got home from Paducah and it was wonderful. Visited many vendors but one was special. I was inquiring about a special bobbin case for my Janome and was all set to buy it. He asked my model and said it won't make any difference on my machine. I just looked at him. He could have made a sale and was nice enough to say I didn't need it. But I bought some other items. This doesn't happen often.
