There was no complaint about the quality of the ingredients, the way it was made, the attitude of the CSR or the time it took to make it. The attitude of the CSR became a problem when they failed to correct your child's mistake.

So, you can't call this "Awful Treatment", or the opposite of "friendly and helpful." It was kind of neutral. They produced the product as requested. Could they have gone out of their way to make up for your child's mistake? Of course, and that would have been excellent customer service.

I think that failing to make an exception isn't awful service. Exceptions aren't advertised on the menu. To me the message to the child is "be careful when you order, so that you get what you want."
