Burger King

So today 07/17/2020 at 6:30, best guess because the rude manager refused me of a receipt
I placed an order for a number 7 meal deal for my son, as Advertised $5.71 for the meal on the exterior menu board. When I arrived at the window to pay it was over six dollars. So even though I already knew this info I politely asked does the state of Oregon have sales tax, the young man informed me no that Oregon does not have sales tax. So I asked then why would my order be over six dollars because the menu board clearly states the price of the meal $5.71. He then proceeded to get his manager who I informed that he is false advertising with such incorrect prices. He then informed me that it is not false advertising, I'm very offended that he insulted my intelligence. False advertisement is misleading, false information to advertise products or services to consumers. I then informed that I do not appreciate being insulted and suggested that he corrects the prices as it is misleading, FALSE ADVERTISMENT.
If Burger King is comfortable promoting this type of behavior cheating their customers then I will no longer return. Burger then in turn is no better than the corrupt individuals in Washington.
