Even though that is the company policy, it probably still depends on which McDonalds you go to. Some cashiers will happily comply, where I can imagine others giving you a dirty look and rolling their eyes when they turn away from you.
I’m thinking of the common scenario where “The Ice Cream Machine is ‘Broken’, sorry!” Meaning, none of the staff have the time or the will to take that machine apart clean each part and reassemble it. I still like their burgers and fries once in a while. It’s usually fresh enough for me.
Yep.....no telling what little ‘extras’ you might get, for asking for fresh fries.
And in certain "urban" areas, if you are not of the same ethnicity of the workers, you will get a fresh order - an order with some fresh spit in it. After all, they are just following the customer service Jesse Jackson gave when he worked at a fast food restaurant.
