how do you get them to add condiments when they dont answer phone calls

That's a good question, and I think they should but Burger King is a fast food restaurant, it means that price is considerable low and the quality of food and service is also. I got two burgers two fries two sodas for around $12. I think the do good considering the price.

Is there a note section in the order menu where you can ask for extra condiments or an option to pay for extra condiments?
