OK, look. Here's the deal. People are trained in fast food places on how to make standard food items. They are then pushed to make them as quickly as possible so that they can make them without thinking. This causes mistakes. The mistakes are never going to go away. If it bothers you that much don't go there, so the lines will be shorter for me.

But, it's funnier to make a big stink thus making you wait longer for your food. :p :D
