Mind-Reading
While this business owner is right in what he says, we feel like he’s a bit too aggressive. He could’ve said the same thing in a less aggressive way, and the message would’ve been just as clear. We’re not saying that he’s wrong – it’s her fault for not reading the description of the dish – but he’s basically calling her stupid!

Even when the customer is wrong, shaming them publically and calling them stupid can’t be good for business. We can’t imagine many people would read this response and feel inclined to support this business owner. It’s always better to stay classy and treat people with respect, even if they are wrong and you are right.
