I have no experience with Round Table.
Worked for a Pizza Hut (Ralston Purina was the parent company, I believe at the time) bake shop that did deliveries only.
This was back in 1986.
Some products/ingredients were frozen or canned/vacuum packed, and the rest were commercial "pacs" that came in refrigerated, with the exception of the dough, which was made fresh daily.
It's a production line pie, with everything measured and assembled according to the "pretty picture" instructions, and then sent through a conveyor belt oven.
The quality of pie depends on the "cook/assembler", as that's the only real variable.
Some people take some pride in a nice distribution, or presentation, of the ingredients, and some just couldn't give a rand rat's patoot how their product comes out.
The person making the pie also can be a little generous with the goodies, should they be so inclined.
The Pizza Hut product is generally made with decent quality ingredients (gourmet it is not), and their goal is consistantly good (not great) pizza, delivered to your door within a reasonable time period, hot, and ready to be enjoyed.
I still order from them on occasion, and am generally not too terribly disappointed.
That being said, if you have a Papa John's available, they sell a good pie, too...
Note: The bake shop personnel do not (or didn't use to) see any portion of the tips given to the driver, and generally make minimum (or just above min.) wage.
Which, was sort of funny when I went to apply, as I was taking a second job to help pay some medical bills, and the manager noticed that I was already earning about 1.5+ his salary in my day job...
I might be suffering from CDO.
It is just like OCD, except the letters are in alphabetical order.
Just as they should be...
