I've worked as a both a line and short order cook.
Some people can not be made happy.
And I'll tell you this, if my order is screwed up enough that I won't eat it and have to send it back. I cancel my order completely and if possible go elsewhere.
I'll eat the salad bar if they have one, but nothing out of the kitchen.
Cause some cooks will do nasty things to your food if sent back.
