Answer most carefully.
The true root cause of all wars, pogroms, and inquisitions [can be found in a fast-food restaurant].
I reject the straitjacket of simplistic binary choices that you would force upon me.

An inability to get laid.
Obviously the only way to go is to eat your burger first, cuz if you eat all the fries, you might not eat the burger. Then your parents will not let you order fries anymore…
Seriously, my folks totally ruined eating for me. It took 30 years before I could eat a little a bit of burger, have a couple fries, back to the burger. I still tend to eat my vegies first, then the meat, then the best thing…the taters!
No one really argues whether place A or place B has the better burger. It’s usually clearly a tie or clearly one of them wins. But fries? That’s when the blood is spilled.
Fies, definately fies.
I never eat all of one thing and then all of another thing. Does anyone really do this?
My husband does. He’s a little obsessive-compulsive. I’d alternate but start with fries because I love fries.
There’s no option for onion rings. 
I’ll eat most of the fries first. Fries are nasty when they get cold and the burger will stay hot longer.
Well, it depends on the type of fries. If you have the nasty mushy kind, they need to be hot, and should go at the same time as the burger. If you have the light golden-crisp kind of fries, they can wait till after the burger.
I vastly prefer the light golden-crisp kind.
Fie upon thee, wiseass!

Inferior Cola killed them all.
Fries first. Save the best for last.
Eggs should be cracked at the big end, and only at the big end.
In regards to hamburgers and their more delicious cousin the cheeseburger, what someone needs to do is think up of a clever way to keep the hot side hot and the cold side cold.

And fie upon these choices! I go back and forth if I’m eating them (i.e., a bite of burger, a few fries, a bite of burger, a few fries, etc.). The only way you’ll stop me from doing this is to pry the burger or fry out of my cold dead hand!
The obvious solution is to remove the top bun of your burger, stack the fries, replace bun and enjoy.
Quite easily arranged. Guards!
I never eat one and then the other, I go back and forth. But I always begin and end with fries.
