A Reddit user claiming to be a former McDonald's worker has revealed what he says is an old company trick to give customers fewer fries.
A thread on the website entitled "What did your job ask you to hide from customers?" revealed a potential fast-food secret when one user wrote: ""I worked at McDonald's and they taught me how to pinch the fry carton just right while putting the fries into them so that it looked full, but actually wasn't."
The anonymous Reddit user went on to explain how one customer noticed the trick one day.
"He shook the fries out into his bag and poured them back into the fry carton himself and it only filled up halfway, so I had to give him more fries.
