>We should charge an additional fee for them. There is no way they will pass that extra cost down to the consumer. They won’t have the nerve.

This is complete nonsense. Of course they will pass extra costs onto customers. The only way that would not happen is if supply is completely inelastic (they cannot change how much food they deliver, for any amount of money) and/or demand is completely elastic (food sales would drop to 0% if any of the fee goes into the final price of delivered food).
