So, if you want to work for change, the first thing you need to do is to stop spending money in those stores. Every dollar spent at a business is a vote encouraging them to keep doing whatever they're doing.

The second thing to do is to let corporate know you're not shopping there and why.

Those things won't have a huge effect unless lots of people do them, but they'll have a much greater effect than harassing the poor front-line workers.

I've never experienced that, personally, so didn't think of it. I just say "no" and that's the end of it every time.
