Burger King Not Respecting Customer Rights

While I was waiting in line, I received an important phone call, I only spoke for 28 seconds. By that time it was my turn and I said to the cashier for a second and asked for permission. He tried to get the customer right behind me, and I said I had finished speaking and it was my turn. When the woman in the back said you've been talking for 3 minutes, I just made a short speech, I said I was choosing a menu, but the woman was still not silent. On top of that, the cashier tried to pick them up again. I am so bored. I won't buy anymore, I don't recommend Burger King to anyone anymore.
