OP asked the price and whatever employee was there just (lazily?) said the most expensive price, which caused the outrage.
I suppose it would save from having the cashier scan it and outrage at the front end from the employees perspective...."they said it was cheaper...I demand to have it for the employee-quoted price!"
If unsure, one cam match the product UPC with the shelf label. Who knows, the employee could have been newly hired off the street recently due to demand.
However, it seems many stores are starting to keep their reserve stocks of paper products on the shelves now so they can start lining in the products in their proper spaces now.
