Insane numbers. You don't get tipped $8, they don't have to raise the costs by $8.Higher operational costs = higher product and service cost.
$20 for the pizza
-$3-5 gas fee
-$3-5 vehicle maintenance fee
+Sales Tax.
The pizzaplace next door will figure they are not spending that much on gas or maintenance, so they'll charge less. If you don't want to lose customers, you better not overcharge.
At the end the market will not allow this.
