>Food vendors raise rates all the time but no one would pay a 3% food cost recovery fee when visiting a restaurant. Its the cost of doing business.

They just lower the portion sizes, get rid of expensive ingredients, increase prices, or all of the above.

Any cost will be passed down to the customer. Including the "cost of doing business". The problem is when the cost is not disclosed upfront. If I am buying a $12 burger, it's a $12 burger. Period.
