Carls Jr. is much more accommodating. I like to order their spicy chicken sandwich, on sale for 99 cents. I have them hold the mayo, then I ask for two packages of BBQ sauce, and viola! A spicy BBQ chicken sandwich for a buck.
Taco Bell for a while had a zesty nachos for 99 cents, while the same-size normal grande nachos was 1.69. So my daughter, would just order it with cheeze and no sauce.
