The video uploaded to Reddit on Sunda shows them order 10 of the $1 burgers without patties, and end up with a free $1 burger.
When you remove the patties, it gives you a $1.10 discount for your bun, cheese, sauce, and pickle.
Order 10 of them you pretty much get a $1 credit.
Don't worry about food wastage either, the two guys said they ate the meat-less burgers by putting in a bunch of fries and making them into chip buttys.
However, some Reddit users weren't impressed, warning people to not exploit the loophole.
“Well if the people actually eat the burgers with no patties it just works out well for them. If they're just ordering all that for a single free burger then that's messed up,” one user posted.
“Clever, what isn't so clever though is to post the method of getting free food for millions of people to see, give it a day or two and it’ll be fixed,” someone wrote.
we're sure the loophole will soon be fixed, so if you want free Maccas, get on it quickly!
