A man in restaurant says:
"Two over medium, please"
He hasn't said "over-medium" what!
So what does it mean "over-medium"?
No, it's not "over-medium."
"over" means flip the eggs over (instead of leaving them the way they were cracked, which is "sunny side up")
"medium" is how thoroughly they should be cooked
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
