I had one years ago leak yellow dye onto my new bra, but we got it off. I think we used a hammer, I was only about 17 & tbh there's every chance that one wasn't paid for
Back when we bought stuff from Rivers though, they didn't take one off DH's shoe I think. We took it back straight away, then got home & realised his pants had one too Had to get MIL to take them back coz we lived 2 hours away. They look alot stronger these days, lol.
