I have a story about Knott's Shoes (in the Mall!). I've often bought my expensive kitchen clogs there - buying them over the internet doesn't always get the right fit.
I bought a new pair of Danskos there in June, and ever since I bought them, the right shoe squeaked with every step I took anywhere. "There's something sticky on the bottom," people would say. It sure sounded like it, but believe me, I washed the bottom of that clog so many times (once I even took sandpaper to it), so I knew that wasn't it. For awhile I thought "once they're broken in, it'll stop squeaking" but that never happened - and believe me, I wear them at least 40-50 hours a week.
Finally one day I overheard students saying "you can always hear her coming down the hall, her clog squeaks!", so I decided to take some action

. I drove over to the Mall (this was in October!) and went in and asked them if they could do ANYTHING to stop the squeaking. They had me march up and down the six foot linoleum strip in front of their register for about 15 minutes. All the folks that work there (they're all in their 60's or older) were bent over, hands on their knees, watching me walk back and forth and back and forth, listening. They took it in the back a couple times and injected something in between the layers. BUT IT STILL WOULDN'T STOP SQUEAKING.
So I sighed, and thanked them for trying, preparing to go. To my total shock, they said "oh, no, we can't let you leave here like that!" and went in the back, came out and presented me with a brand new pair ($120 price tag!). "I'm sorry, I don't have the receipt with me...I don't even think I have it anymore," I said.
"That's okay, we believe you. Here. Enjoy. We'll get OUR money back from Dansko."
Unbelievable! I won't be buying clogs anywhere else for a long time.
