Holy Poo Poo Batman!
I will say this, if the owner of a company ever spoke to me that way, especially in a public forum, not only would I never do business with him or her again, but I would do everything in my power to make sure nobody else I knew did either. I don't care if Heather was right or wrong in making her comments. If you want to stay in business, you just don't speak to customers that way, current, former or otherwise.
Just my $.02.
