Shop local and you can! My farmer's markets and greenhouses don't care about my feet. WalMart ... not so much!
Yeah, I got into it with a manager at Walmart. He told me I had to wear shoes and saud it's the law. I proved its not so in our state and he got nasty. I told him I'd wear shoes when people no longer put their dirty dogs in the shopping cart where I might be putting my groceries and threatened him with the health department backed up with pictures. He ignores me and I take off my shoes if I feel like it.
