Yeah, those fast food joints realise that the drive-throughs should be fairly speedy, but they do tend to let you know that whatever you order is what you should get whether it is straight off the menu or you want extra this and less of that.
Personally, I'm not crazy about my pickles in a burger so I ask for them on the side. If it comes inside the burger, I don't throw a hissy fit like Boomer seems to have done. I simply pay, find a spot I can sit, and then take the pickles out. Not a big deal. If it seems to be a habit with the joint to screw up my order, I simply quit going there rather than ranting.
