An enterprising entrepreneur would take advantage of this.
Post a placard of the stupid nutrition information for each pizza with a single type .... the basic pizza is bread and sauce.
Then charge whatever for each topping and list nutrition information for each topping, singly. Charge a dollar - whatever. If the patron wants the nutrition information for each additional topping to the standard pizza, charge them a $1.00 to look up on the computer what that is.
Blame the extra expense for those fart-sniffers who’d buy the damned pizza anyway, but want to be a horse’s ass, on Obama and his SAB wife.
I'm afraid competition in the Dreaded Private Sector has already driven the price of that service to zero. And the customer doesn't even have to visit the store.
