She wanted to smack the woman's face by the knowledge she held when it came to the charm stones but answering the woman with facts would only put her in a problem. Any words related to 'witch' could bring her unneeded attention that had the possibility to blow up by gathering more people with a look of suspicion.
At the same time, Penny couldn't accept that she was selling something that was not charm stone but mere stones that were polished that didn't even hold a shine.
"Come on tell me?" demanded the store woman, her narrowed eyes glaring down at Penny.
"This woman is selling fake stones that has nothing in them," Penny spoke loud enough for the other passersby to come to take a look at it, "If what you are selling is to be true, then demonstrate it to us."
The woman rolled her eyes, "Just because you aren't willing to pay for the charm stones you want to create a scene in front of my shop while accusing me that I am not selling the right stones."
