Unethical dance mom?

I’m going to go into the local Verizon store and sell my own phones. I’ll even bring a little cardboard stand, it’ll be perfect.

Seriously, selling something like this is rank. You don’t have to curse her name to the Moon, but you do need to be firm and direct with her.

I think you’re probably right - she obviously is someone who didn’t think that she shouldn’t be doing what she was doing (when most of the population does), so she’ll likely try it again.
