I've learned the "order" that my local BK want's to hear me say in. I can't order a #4 with cheese extra pickle no onion and a diet coke. I have to order #4, medium size, diet coke, add cheese, heavy pickle and no onion.
part of the problem is the registers they use - the registers ask them the questions in a specific order and they can't bypass question 1 to get to question 2 or 3 - just because the customer blurted out question 2 or 3 before question 1.
In an attempt to make their systems fool proof, they've created fools.
