Let's pay extra $$$$ to buy and keep two kind of grills operational at same TIME. If Vegan have issues with that are they happy that bio waste from animals is used to grow their beans? For me it sound like Vegans are the devil getting burned here by touch of holy water
That does seem like something the employees should mention, but if you are THAT vegan you shouldn't be supporting burger king in the first place with your purchase.
I don't believe they tout the Impossible Whopper as Vegan, but Vegetarian. A recent review of the burger by like ZDNet or some source like that I read this week states that the patty is cooked on the burners along with beef patties as well so it is not vegan.
