Why do americans put ketchup on everything?

I only use it on 3 things really. Burger, fries, and eggs

It's frequently too sweet for me, but I'll mix it with other things to make interesting dipping sauces.

That is a very good question actually! Bad habit i guess!

Only on Burgers and hot dogs for me. And I don’t all the time.

I don't hardly ever use it.

It's good on burgers

Because sugar I think.

I hardly ever use it and certainly not on burgers or dogs.
