I had this same problem with KFC, I wrote down exactly what I want, in perfect prints that is so easy to read.
I got the order wrong. I reported it back to the cashier - guess what, that cashier is actually the manager! He have me a bad attitude so I called KCF Headquarter and explain what happened, send them copies of receipt and my notes, etc.
Two weeks later, that manager got fired by KCF headquarter.
