Since the bun is already “cut” this is the only logical way to do it given the instructions. The issue isn’t misunderstanding, it’s the instructions being bad. It’s like telling someone to cut an already-sliced loaf of bread.
It is really really difficult to write good plain text instructions for other people to follow.
It’s a great experiment to try at home, or with a coworker - write up some directions for a task that the other person doesn’t already know how to do (something non-critical preferably) and ask them to try to complete the task per the directions without any other help. It is amazing how many assumptions we make about what seems obvious to us.
I get pushback at work about how I need to “be better at working with incomplete or vague instructions”, but “if it’s not in the spec the behavior is undefined, and you get what you get” is unacceptable.
Still mildly peeved about when product complained a list wasn’t sorted alphabetically. They’re lucky the order was deterministic at all
