You get mayo every time even when you distinctly say “no mayo” they will show you they give you mayo

I have on several occasions ordered long chicken burger with no mayo and lettuce at several Burger King outlets and each and every order their staff get it wrong. No matter how many times you explain to the teller, you still get mayo. They don’t read. Tonight was the last time I order BK. On all my Mr Delivery orders they confirmed no mayo, but tonight was the last time we ever order Burger King.
