You can tell right away if you've got fries that have been sitting about at McDonald's - they can be cold, stale and a bit of a disappointment.
One way that customers have tried to guarantee fresh fries is to ask for them without salt. Since the fries that have already been made are usually already salted, it means there's a good chance you can get a freshly made batch - and if you still want salt you can add some afterwards.
However, according to an ex-employee who posts on TikTok under the username @jodessy, this isn't the best way to get your hands on fresh fries, writes The Mirror.
