Lol, I never thought about it before reading your post, but I guess that's psychologically why I always eat all of the French fries first and then start on the rest of the food. You're onto something here!
The problem may lie in the fact that the fries are too skinny. All these fast food joints have skinny fries for fast cooking. You need thick chunky type fries, they lose heat slowly, therefore you end up burning your mouth. They also taste better, like potatoes.
There we go! Great idea! And with my winning ways and delightful humor, they'd want me to be the spokesperson to sell the warmers directly to the public and then I'd find my dream man (he was on the film crew for the TV commercial) and I'd be in a wonderful relationship - -- see how crazy my imagination flies? Ha!
