My goodness. Just read this news article.
So first you go to a restaurant and get a bad meal. Then they replace the meal, but charge you for both dishes, and they're rude. Then they frame you with a sex-site page and tell your boss and coworkers about it. Then they lie and say they didn't do it.
What a nightmare.
I hope the guilty party gets the full weight of the law, and that the restaurant is closed down. That's no way to treat a customer.
