You're right about that. I remember when I first developed what we called the "pizza radar," where you just knew it was time to shift the pizzas around in the oven, or when a pizza was done. Workers at Pizza Hut always thought it was cool when they developed it. Those were the days before the "conveyor belt" ovens.
Can you imagine OSHA inspectors today, if they saw us reaching into the ovens with a pair of channel lock pliers to pull the pans out of the ovens, without wearing some sort of heat protection on our hands and arms!

"pizza radar,"
And it went off whether there was anything in the ovens!!
I can't count the times I took off for the ovens to check and there wasn't a pizza in sight. I wasn't the only one that did it either.
I still have scars on my arms from those old ovens!
