Depends on the company I guess. The company I work for has a $2.00 delivery charge -- even for credits. It'* just the company policy that I'm forced to follow. I can't even place the order without that charge being there, and even with a 100% discount, the $2.12 (after tax) is still there. To compensate I usually include something that the customer didn't even order that they may want. (like free wings, 2 liter, sticks, whatever.)
For the two hour rule, that'* the longest that certain types of food that need to be refrigerated can sit out at room temperature before they start
to grow bacteria. For pizza, almost all the ingredients come to the stores pre-cooked and frozen. There is very little chance of getting sick, even if the toppings were to be eaten pre-cooking. It would take several hours after the initial two hours for harmful amounts of bacteria to grow that could make you sick. This isn't to say that it'* ever a good idea to leave food out, but still.
