Hi Phil,
I suppose it depends on what side of the fence you are. If I were a restauranteur, I would put the taste and quality of the food above that of the convenience and cost to make it. Choosing to charge more for a better plate of food.
On the other hand, if I were the proprietor of a take-away, I would opt to choose a quicker more convenient and consistent method to produce a cheaper plate of food. After all, you can't make a packaged meal (curry in a foil container) look good and nor does it travel well either.
Just my view though.
