Burger King

I work late hours and rely on fast food. Last night 7/10 at 9:30ish, I went to burger king. Plan was to order 4 tacos, a dlb whopper combo and 2 chicken sandwiches. Tacos are frozen and they won't serve them to me. I went to mcdonald's. Tonight 7/11 approx. 11pm I plan to try burger king again. I really want to try the tacos. Bf too. Order is similar except I want 6 tacos. Again... No tacos. And the employees aren't very accommodating and very rude. I went to taco bell. How it when are we supposed to try your new products in this store?
