Burger King, Brandon, MB

As I work late shifts, and sometimes I don't have time for dinner, I have stopped 3 different occasions to grab a couple whoppers for a late dinner after I drive home. I'm an hour south of Brandon. Twice now going through the drive through, they have screwed up the toppings, (have it your way), on my burgers. The last time I thought, get out of the car, maybe face to face, they may understand what I want on my burgers. Three times I asked, and it was repeated back correct three times. When I got home, again the toppings were all wrong..My son is allergic to mustard and mayo, and bit into the burger, epu pen to save the day..If it's that difficult, just tell people you can only make burgers with all the condiments your restaurant offers...Final time, I would rather pay double the price across the street for a burger made actually my way..
