McChunk

I'd like an extra-size McChunky's combo with barbecue sauce to go please.
Yes, barbecue sauce.
Look, I know, firstly, that you have barbecue sauce, because you offer it as an option with the chicken strips. I know secondly that this barbecue sauce is free with paid order, because it doesn't cost extra when it comes with said chicken strips. Therefore I can conclude that you have an ample supply of babecue sauce, and I would like some on my burger! Q.E.D.
... Do I need to draw you a flowchart? Don't think I won't do it.
I don't care that you think it's weird, it's what I want!
Look, I am the customer. I pay your slave wages! The very absolute least you can do for me is pretend that you won't screw up my damn order!
Thank you. I am honored to be able to pay seven bucks for the priviledge of dealing with people like you to eat my heart-attack-inducer of choice.
Because it is a damn tasty burger is why.
